A character who wants to look dangerous has several choices in outerwear — long swishy coats if you want to look dashing and mysterious, leather jackets appeal to the James Dean wannabe in all of us, stylish dark suits look aloof and professional — but not sweaters.
Whether because of their fuzzy texture or sweaters' association with gifts from one's grandmother, sweaters do not look intimidating. In fiction, a character who wears sweaters frequently is often some variety of nerd, otherwise cute, or at least approachable and non-threatening. Sweater vests, in particular, are normally a sign of extreme nerdiness.
Keep in mind, however, that while Dorks In Sweaters don't look dangerous, that does not mean they are necessarily harmless. The various Hidden Badass tropes may apply. A character may look like this when he's (or she's) obligated to wear the Homemade Sweater from Hell. This trope can overlap with Sweater Girl if the lady in question is more of a Hot Librarian than a conventional bombshell. Also The Smart Guy of a group usually could dress this.
- Sarada from Naruto is of the "nerdy" variant. She's a studious and booksmart girl. Her casual clothes during her days at the Ninja Academy were a tie and sweater-vest (combined with her glasses). This attire however hasn't been shown outside the Distant Epilogue of the manga (which takes place a few years before Naruto Gaiden). The Boruto anime retconned her clothes to be something more similar to her ninja attire.

- In the non-fiction book Stitch and Bitch, Debbie Stoller invokes this in her explanation for the superstition that knitting your boyfriend or girlfriend a sweater dooms the relationship: if you put all that work into a sweater but your special someone never wears it because it looks wrong, you could end up resenting each other.

- Poked fun at in a MADtv sketch making fun at Freedom Writers and the Save Our Students trope. The "Nice White Lady" wears a non-threatening sweater and floral blouse, which gets mentioned by a student during a rant.
Look at you in that sweater-vest you're wearing and that adorable patterned blouse! What you think is gonna happen here? You think you gonna inspire me? You think you're gonna break through my "tough girl" act and teach me the beauty that's inside? You think you gonna make me do and feel things that I've never had before? All because you're a non-threatening, kindhearted, beautiful white lady?

- Darkwing Duck: In his civilian identity, the 'terror that flaps in the night' wears a pink and green dorky sweater.

Also, he (and all his evil counterparts) all wear a turtleneck sweater underneath their suit jacket costume.
- In The Fairly OddParents, Timmy's genius friend, A.J., wears a sweater vest. In Season 4 "Who's Your Daddy", Timmy and Cosmo call the sweater vest a "girl magnet" and when Jorgen poofs himself a sweater vest it attracts the attention of the Tooth Fairy.
