Small chest

I have a small chest

Like Charlotte, your shoulders are rather narrow and you have little chest.
When you buy a bra you generally go for A or B cups.

The trick to follow
You have to add a little volume. The push-up will therefore be your best ally. It will help you enhance your neckline to sculpt a feminine silhouette.

Swimsuit for a small chest

Advice from Mademoiselle Bikini:
For the swimsuit top: fall for push-up swimsuits, underwired models, fringed or ruffled swimsuits that will allow you to expand your chest and create volume. And for the colors too, you can let go, unlike black which tends to slim down. And we want the opposite effect. Dare flashy colors and prints.
You can also turn to headbands, which contrary to popular belief will not necessarily crush your chest. You just have to choose the one that will highlight you and a suitable size so that it adheres perfectly.
For the one-piece swimsuit: everything is allowed, even very low-cut swimsuits that do not look vulgar on small breasts.

To avoid :
Anything without padding or molded cups that are too hollow that won't be filled and that risk creating a gap between your chest and the jersey.
