There are a million factors to juggle when hunting for the perfect prom dress. Dress codes, coordinating with your date, sticking to a reasonable price point, and finding something that makes you feel fabulous are all things to consider — and if you're looking for modest prom dresses, the search might feel even trickier. With the thigh slits, cut-outs, spaghetti straps, sheer corsets, and deep-V necklines that are everywhere for prom 2023, finding a bomb gown that keeps you covered in a way you're comfortable with can require a little more work.

Luckily, some of the top prom trends of 2023 (like ruffles, feathers, and bold colors) are 100% available for you to play around with even if you're looking for a more modest prom dress. And if you find your dream dress but it shows too much skin for your comfort, tailoring to close slits or plunging necklines is always an option. You can also layer a dress with cutouts over a simple bodysuit in a matching, or even contrasting, colors.

If you're currently struggling to pick the dress, you'll want to bookmark this list of the cutest high-neck dresses with sleeves of every length out there on the Internet right now. Some might need a quick liner or an added seam, but most prom dresses on this list won't require major alterations. Scroll down for the most stylish modest prom dresses of 2023.
