Best bikini top styles for small breasts

Having one of the smallest cup sizes, like AAA or AA will make shopping for a bikini top quite a challenge. I find that some A-cup-sized styles can work or a non-cup-sized style.

Racerback bikini top

Racerback tops work well on smaller breasts.

They fit firmly around the chest and will give a sportive look.

Some tops have pads that are removable. A racerback style top is ideal to add extra pads if you like. The good thing is that the pads stay put because you won’t have to worry about traps falling down your shoulders.

This strappy x-back design bikini comes with a wire-free supportive top with soft foam cups.

Triangle bikini top

Triangle bikini tops can be a good choice for small boobs. You can adjust the straps the way you like them. The smaller your breasts are the more the cups will cover your breasts.

Many women love this style for the natural no push-up style.

Push-up bikini top

Look for push-up triangle styles. Some A cups might work for smaller cups as well.

Adding bikini pad inserts lets you take control of how much cleavage you want. Of course, there’s a limit to that boost when having small boobs. But then, I find a little cleavage can be very sexy.

Bandeau bikini top

I always have a bandeau top in my suitcase when on holiday. When you have small breasts this style always looks good I think. The style will not press your boobs together. The wider set cups will not flatten them either.

Classic Black Bikini Top

Black is always a good choice for a bikini top. It has a classic feel to it and is not showing off.

You don’t want a top that is too big, but you might add swim inserts. Also, look for triangles that wider set.
