Bram Stokers Dracula has several, particularly worn by Mina. Her blue dress had lots of darker blue embroidery on the sleeves and bodice, and a skirt with loads of fabric bunched up different ways at the front and back. Her red dress was even more bunched up in the back, with lots and lots of frills, ruffles, and pleated hem. Her green day dress had leaf-like trimming on the cuffs and collar, and the back of the skirt was folded repeatedly to give an appearance of alternating green and white diamonds. Lucy also got a few, like her white dress with the puff sleeves and loads of lace, and her funeral dress with the massive neck ruff.
Use in an interesting way in the film Diane. Diane de Poitier's dresses are opulent, but Catherine de Medeci's dresses are more so. Until one day, to show her favor with the king, Diane shows up in a dress just as grand. Even the ermine trim on the skirt is identical to one on the dress Catherine is wearing at the same time.
The outfits in the 1984 Dune film are pretty elaborate. Much of the ladies' dresses were based on renaissance gowns, hoop skirts, trimmings, collars and all.
Miranda Frost's ice-themed dress in Die Another Day, with lots of fringe on it looking like little icicles. Then just throw on the white fur wrap to complete the look.
Queen Elizabeth in Elizabeth: The Golden Age is adorned by an astonishing sequence of unbelievable confections. Some were in what the producers cheerfully admitted were wholly historically improbable colours, just to look cool.
Giselle's would-be wedding dress in Enchanted has Giant Poofy Sleeves, lots of lace petticoats, a frilled underskirt, ribbons, and butterfly decorations.
Nancy's actual wedding dress to Edward is also pimped out, with smaller poofy sleeves, bows, and ruffles.
Queen Tara's gorgeous petal dress in Epic . In fact, it actually seems to come as a package deal with being queen. When a new one is crowned, she magically gets a similar dress.
In the finale of Girls Just Want to Have Fun, Natalie Sands wears a designer made outfit that's loaded with sequins and other trimmings. She even tells the staff of the show she's competing on that it's a designer original.
Gone with the Wind has several, most worn by Scarlett. Her first dress is a frilly white one with green ribbons. Another dress is a white one with black trimming and an ermine muff. One is all red, including the loads of feathers, that Rhett makes her wear to a party. Vivian Leigh even got a special dress made just for the Atlanta premiere, that was black velvet, had a white ermine neckline, and puff sleeves made of ermine tails. Then of course there is the green Curtain Clothing dress.
In the Ginger Rogers film Lady in the Dark, she wears a dress with a mink skirt and loads of jewels on the top and lining the skirt. She had to wear an altered version for a dance sequence in a later scene (the skirt was just lined with red fabric), so it wasn't too heavy to dance in.
Mae West wore many fancy dresses in her film, with varying amounts of lace, frills, sequins, and fur, with fur often edging the hem of the skirts, which few actresses could pull off as gracefully as she could.
Both the 1930s and 2000s versions of Marie Antoinette. The dresses have various amounts of ribbons, frills, feathers, fur, and jewelry.
The Queen wears a red peacock-themed dress with hanging sleeves, white lace on the cuffs, flared out shoulders, white peacock feathers embroidered on the sleeves and bodice, a white collar with the fabric given a feathered cut, and a white peacock tail as a second collar (that's detachable).

Another dress is a yellow dress with hanging sleeves and a huge neck ruff.
Then there is her white wedding dress◊ with the fabric on the bodice and skirt bunched and cut to look like lots of leaves, and large gauze sleeves.
In Pirates of the Caribbean, Elizabeth gets two of these. One in the first two movies until she becomes a stowaway, then again, to some extent, when she is on Sao Feng's ship.
Buttercup gets herself a stunning white, lace number towards the end of The Princess Bride. (The book seems more intent on making fun of this trope.)
Ozma's dress at the end of Return to Oz, which was based on the outfits John R. Neill drew for her in the original books. It has lots of gauze, beads, flower-like trim at the bodice, and feather-like trim at the shoulders.
Each of them is based on a Real Life dress, incidentally. One of them resembles a Mongolian wedding dress.
All of her costumes—and their real life counterparts—are explored in great detail here.
To elaborate on just how many and how costly her dresses actually were, at one point in Phantom Menaces, Obi-Wan estimates with all seriousness, that if they were to sell all of Queen Amidala's wardrobe at the time, they very well might fetch enough local money to purchase the repairs they needed. The same amount of money as the grand prize of an annual, high-stakes podrace.
