The blackness of my hair tells you how I feel of your opinion.
The Aloof Dark-haired Girl is a fairly common character type combining both appearance and personality. They will generally be taller than their peers, more physically developed, and their hair will be very long and dark. Frequently, their skin will in contrast be very pale. They look older and more beautiful and meet a certain classic ideal of feminine beauty combining maturity, a quiet attitude and a combination of long hair and very pale skin.
The Aloof Dark-haired Girl will not merely look older than her peers, however. Frequently, she will also act more reserved and aloof and thus seem more mature, which may earn her some younger female admirers. It is not uncommon for them to be fond of teasing their peers or acting as their big sisters, though in all cases they will still maintain their dignity. Occasionally, she will even look cold and distant, but in this case she is still probably a nice person deep down. Finally, it is essential to remember that despite the usual popularity of the girl in question, they do not seek it out. Instead, people simply gravitate towards them with admiration.
Compare Onee-sama. May lead to Even the Girls Want Her in the right sort of series.
Namie Yagiri from Durarara!! is tall, has long dark hair, and displays an extremely aloof and cold attitude towards anyone who isn't her brother.
Isuzu 'Rin' Sohma from Fruits Basket fits this trope to a T. She's tall, has waist length black hair, and severe trust issues courtesy of her emotionally Abusive Parents. Bonus points for being, according to Word of God, "the character in charge of sexiness."
Konoe Tsurugi in Hanaukyō Maid Tai is the tall and stern head of the Security department for the main character's Maid Corps. She has long black hair and in the reboot her Adjutant, Yashima has a crush on her.
Chikane Himemiya in Kannazuki no Miko. She is tall, graceful, very popular among the girls of her school and has very long dark blue hair.
Ran, titular character of Kazemakase Tsukikage Ran, is a textbook example of this trope, particularly in that she attracts trouble like a magnet (or is attracted to it?) and has a MoeChinese Girl following her around most of the time. However, she dresses and acts in a masculine way, despite looking quite feminine; if she were ever taken for a boy (oddly, no one makes this mistake), she would be bounced right over into Bifauxnen territory.
People are often in the dark about her gender until she starts talking, though.
Mio from K-On!, complete with an all-girl fanclub and also being the tallest of the main characters. However, she's a subversion who's quite similar to Sakaki in that she's painfully shy.
Micaiah Chevelle of Magical Girl Lyrical Nanoha Vivid has long, black hair and is one of the tallest females of the cast. As befitting her traditional Japanese Samurai motif, she is always calm, reserved, mature, and highly respected by other characters who often go to her for advice. Eventually, gets a Lampshade Hanging by Nove, who expresses surprise that Micaiah knows how to cry.
Nove: Micaiah-chan cries too? I just can't imagine that. Micaiah: How rude! I may look like this, but I'm still a girl, you know? I cry when it's time to cry!
Akira Ookuchi is tall, very quiet and has very long dark hair.

Ogasawara Sachiko in Maria-sama Ga Miteru is tall, has long purple hair, and is described as cold and aloof despite being universally admired throughout her school.
Maki Izumi from Martian Successor Nadesico is something of a subversion of this. Physically speaking, she's quite attractive; however, she's always cracking bad puns, has a habit for playing the ukulele (terribly), and nobody seems sexually interested in her while she never shows any sexual interest in anyone else. At least, not until the episode where everyone's repressed personalities come to the forefront and her sexual side tries to convince both Akito and Akatsuki to have sex with her. Of course, this is also the episode where it's explained that she's repressed said sexual side because both of her fiancees died young and she's convinced if she opens up to anyone, they'll inevitably die as well and she'll just be alone and heartbroken again.
Nico Robin is the third tallest member of the crew, has long flowing dark locks, is widely considered to be the most attractive member of the crew, and has an austere and sophisticated personality.
Boa Hancock, who is even taller, has long black hair, is extremely aloof to anyone who isn't Luffy and is considered the World's Most Beautiful Woman by both men and women.
"Mona Lisa" Komabayashi and "Vampanella" Hoshino, membresses of the Sorority in Oniisama e.... Fukiko Ichinomiya are Rei Asaka are both Tall Blond And Bishoujo.
Mariko Shinobu has the looks, but she's younger and more...troubled than the standard, but let's give her a few years. Her mother Hisako as well as Nanako's mom fit quite well, whereas Kaoru Orihara has some traits despite being The Lad-ette most of the time. And the grown-up Nanako from the last episode of the anime resembles the archetype VERY strongly.
Suzuka in Outlaw Star is tall (almost six feet), has long black hair, the most attractive female in the main cast and even after joining Gene's crew she prefers to be left alone.
Lt. Kanuka Clancy from Patlabor has long raven-black hair and acts cool and collected at all times. She's very much The Stoic.

Sailor Mars is black-haired with pale skin, but her characterization only appears in the manga. Whereas in the first anime she is a loud, fiery tsundere, in the manga she's cold, calculating and serious.
Sailor Pluto has long, black hair with shades of dark green, and is one of the most imposing warriors as she's older than the rest. Personality-wise, she tends to be mysterious and detached—traits necessary as she's isolated guarding the gate of time.
Zakuro in Tokyo Mew Mew is tall, a famous model and actress, and has many admirers. She's also a loner who's the last member of the team to be introduced.
Whenever Sunako Nakahara from The Wallflower gains enough confidence to break out of her Super-Deformed mode, she looks like a beautiful and tall dark-haired girl and is able to act very aloof and graceful.
Kagari Ayaka from Witch Craft Works (pictured) has long black hair, and is at least a head taller than the protagonist and most of the other students at her school. Despite having an aloof and reserved personality she's the most popular person in her school and even has her own fan club.
Satsuki Kiryuin from Kill la Kill ticks all the boxes. She has long black hair and pale skin and towers over all the other students, both in height as in presence. She is the Student Council President and she doesn't care about what other people think of her (or her body), but leaves her students in awe because of her beauty and massive charisma. She has a Sugar and Ice Personality, acting cool, distant and arrogant in public, staying in control of her emotions at all times, but allows herself to smile and relax a bit more among the select few she genuinely trusts and respects.
Veronica in Archie Comics who tends to act aloof to her friends due to her social class. Her dad, a self-made man, said he sent her to Riverdale High specifically so she wouldn't end up a snob. It...kinda worked?
X-23 is pretty, with long, dark hair. She's also very quiet and aloof with her friends and teammates, and when she does speak her words are generally short, precise, and to the point.
China Sorrows from Skulduggery Pleasant is very much this trope: she's tall, beautiful, dark-haired, aloof, and can make men and women fall head-over-heels in love with her.
Katniss Everdeen from The Hunger Games could qualify. She is aloof, dark-haired, and admired by many, whether it be her "fans" from the Capitol or some of her fellow soldiers and tributes in The Hunger Games.
Fiona Coyne of Degrassi carried all the pinnings of this trope, just in a western setting. This includes the crossover with The Ojou and some Tall, Dark and Snarky for good measure. She's spent her whole run fighting boys off, even after she came out, and trouble is not of short supply. Her girlfriend even fits the Shrinking Violet (when it comes to their relationship) trope.
Ziva David from NCIS is a tall, beautiful woman who is a definite Ice Queen to her teammates, except for Abby (whom one might expect to fit this trope instead). She mellowed down considerably to the rest of the team by season 7, however.
Lady Mary Crawley of Downton Abbey is a textbook example: a tall, dark-haired beauty, persistently frosty, haughty, and detached, with several suitors that we've seen, to say nothing of her sister Edith's persistent but almost entirely one-sided rivalry.
In the Heike Monogatari, an account of the Genpei War, Tomoe Gozen, a female samurai of the Minamoto clan, is described as "especially beautiful, with white skin, long hair, and charming features". She was also recorded as being "a remarkably strong archer, and as a swordswoman she was a warrior worth a thousand, ready to confront a demon or a god, mounted or on foot." She was one of the last warriors standing at the Battle of Awazu, even outliving her master who was struck down by an arrow during the fight.
Yukiko Amagi from Persona 4 is a subversion. She has long, black hair in a traditional Hime Cut and is very popular at school for her beautiful appearance. Her classmates admire her, but find her impossible to approach romantically since she rejects everyone. However, Yukiko is revealed to be an utter goofball who bursts into laughing fits when hearing silly jokes, instead of the seemingly perfect Yamato Nadeshiko she's thought to be. Not only that, but when she's comfortable with the people around her, she gets very excited about telling scary stories.
Lulu from Final Fantasy X. She is cynical, stoic and snarky to boot. She initially appears detached from everyone other than Yuna, and acts dismissive even towards her childhood friend Wakka.
Ikaruga from Senran Kagura. Physically she is the closest to the ideal of Yamato Nadeshiko beauty, she is the most mature of the Hanzo girls, and some family issues has made her some kind of a loner, or at least someone who have difficulties opening up to the others (she's already recovering by the beginning of the game, but remains somewhat aloof). Subverted in the anime, where the staff loved to make fun of her personnality.
Orihime Tsukishima in Kara no Shoujo who is the tall, elegant, aloof, and refined Student Council President. She's also highly repressed and ends up starting a prostitution ring involving herself and girls that she knows who feel the same way.
Tsugumi from Ever17 is tall, has long dark hair, and takes quite a while to warm up to the other characters.
Kotonoha Katsura from School Days is a subversion; she looks the part (is tall, dark-haired, and buxom) and has a number of admirers (mostly male). People assume she's aloof and uncaring because she keeps to herself a lot, but the true reason she does so is due to a lack of self-confidence. It's also deconstructed a bit as well; her beauty, apparent aloofness, and popularity with her male admirers mean that most of her female classmates think that she's some sort of seductress out to steal "their" men, which spurs some of them to bully her using almost every trick in the book.
Susan of El Goonish Shive is the tallest girl in the main cast, has dark blue hair (previously dyed, now permanent), and is generally aloof and composed.
When Javert got gender flipped for a short time in Roommates he became this archetype. Tall (the tallest cast member), graceful, with long dark hair and aloof (at times snarky) personality, who was the voice of reason and maturity in the madness. Also many, many fangirls thought it was a shame, when the magic ended.
Sandra on the Rocks: Zoť actually fits this trope very well, in both appearance (she's tall, fairly pale, and supermodel-grade beautiful) and manner (being aloof and controlled); she also has a few admirers, although she earns them by being very good at what she does. She comes at the trope from a slightly unusual direction, though, being Tall, Dark and Snarky and not treating many other members of the cast as friends. The only problem is that her aloofness is prone to being compromised when she loses her temper with other, less sensible characters.
It should be noted that Azula, while fulfilling the rest of the trope's criteria, would be considered a remarkably short example.
Asami Sato from The Legend of Korra. She's beautiful, raven-haired, and much more calm and mature than the other members of the New Team Avatar.
Shego from Kim Possible. She's tall, has long black hair, and a very imposing and aloof attitude.
Ava aka White Tiger in Ultimate Spider-Man tends to act a bit more professional that the rest of the team. This because she needs to keep herself in control to prevent the Tiger amulet from taking her over, and turning her feral.
Daria is dark-haired, aloof, and bases her personality on the dignity of being snarky and superior. According to her own self-image at least, she is much more mature than her peers (an easy claim to make at Lawndale High School) and that's why she has relatively few friends.
