Here Shop With Us, we believe sometimes less is more — and that certainly applies to cup sizes. In many situations, fun-sized busts can be a great choice. You don’t have to worry about chest pain during most physical activity; you can pull off the model look when wearing chic styles; and 99% of the time, you don’t have to wear a bra. We know that the grass is always greener from the other side. Insider’s study found that 71% women are unhappy about the size of their breasts.
Summer can be a challenging time of the year for some, as swimsuits make your chests visible. Use. We set out to find the most flattering suits for smaller busts. As Cosmopolitan says, “Small boobs get a lot of bad press, but actually, a summer with a small pair is a joy”You can read the article to see 14 reasons why.
How we chose the best swimsuits to fit smaller busts
Shakira once sang, “Lucky that my breasts are small and humble so you don’t confuse them with mountains.” Those lyrics were inspirational back in middle school when I was waiting to hit puberty! Flat chest struggles are something I have experienced firsthand as a late bloomer. While I’ve never gone quite so far as to stuff my bra (a classic adolescent move), I used to wear Victoria’s Secret push-ups that were way too padded. Now I know how to find flattering sizes that offer the right balance of support and comfort.
We wanted to ensure that we included options that would appeal to a wide variety of customers when choosing the bathing suits to be added to our list. Swimwear is not a one-size fits all. We incorporated a variety of styles — from bandeau to triangle — so that you can choose your favorite silhouette. These 11 swimsuits will all give you the boost you’re looking for without flattening you out!
