Since I have a smaller band size and a larger bust, I can't wear swimsuit tops that only come in alpha sizing (small, medium, etc). I've tested more than 30 different suits to understand which features actually support your bust. Plus, I've tapped in other testers with different body types and needs to advise on their favorite, most supportive suits.And since I'm from Hawaii and have always been interested in swimwear fashion, I also made sure to include brands that don't treat style as an afterthought. Here are my best tips:Always prioritize brands with bra sizing: If you want true support, your swimsuit should fit like a great bra. It's not always feasible for brands to produce bra-sized swimwear since it drastically increases the sizes they have to stock, but brands like Bravissimo are committed to making every single suit on their site available in sizes 30DD to 40K.Underwire is your friend: If you want your chest to look lifted, underwire is the way to go. Bra-sized swimwear usually has underwire built in, but Lands' End has a collection of DD-cup underwire suits that are incredibly supportive despite the lack of exact sizing.Look for features like thick straps, adjustable backs, and supportive underbands. Low back styles, strapless tops, and straps with no adjustments are less supportive and may be uncomfortable.How we tested swimsuits for large bustsTo find the best swimsuits for large busts, we started by combing through traditional swimwear brands for styles designed with fuller busts in mind, prioritizing options with DD+ sizing, bra-sized fits, underwire, adjustable straps, supportive bands, molded cups, and other explicit support features. We also looked closely at brands that specialize in large-bust swimwear to compare their fit, construction, and size range against more mainstream options.From there, we consulted experts, read through Reddit threads and customer reviews, and asked friends with larger busts about the swimsuits they actually like wearing. We considered how each suit fit when dry and wet, whether it provided enough lift and coverage, how secure it felt while swimming or moving around, and whether the straps, cups, and bands stayed comfortable over time.We wore the swimsuits in the water, moved around in them, and washed them according to the care instructions to see how well they held up. Throughout testing, we paid close attention to support, comfort, adjustability, coverage, durability, style, and whether each suit felt practical enough for real beach, pool, and vacation wear.Editor-favorite picks, tested over two years Best overall: TA3 The LiftySally Kaplan, TA3TA3 makes the swimsuit of 'Shark Tank' fame that doubles as shapewear.
