The Small Bra Guide

Having smaller breasts can make you feel you’re one of the few with small boobs. Well, your not. Personally, I think we could fill up a whole new planet with us Petites.

1. What is a small bra size?

Some people call cup A small, some might even say the same about a B or C cup.

It depends on your perspective. Boobs come as small as they like.

It’s what nature is all about. So, how small is small anyway?

2. Cup AAA and AA bras

There is no such thing as breasts being too small. There’s a bra for every woman.

Read all about the cups AAA and AA and where to shop!

3. A cup vs B cup

Different bra sizes can be very close

A little change in your measurements could mean a different bra size than you’re wearing at the moment.

You cannot just say that a B cup is bigger than an A cup. Why are A and B cup bras that close?

4. Bare Reality

I want to mention the work of Laura Dodsworth. She published the book Bare Reality, an amazing book about women and their breasts.

Laura spent two years photographing and interviewing 100 women about their breasts, bodies, and lives. Women from all walks of life took part, aged from 19 to 101, sized AAA to K, from a Buddhist nun to a burlesque dancer.

The book and this video are the best, and really for everyone to watch, both men and women. You’ll find her books on Amazon

5. Teen bras

Teen bras may have lightly padded cups. Some have flexible wires.

6. Triumph petite bra collection

Triumph collection Petite | AA cups

Triumph is one of the lingerie companies that also have a collection of bras in AA cups. That’s very good news for petite women with this cup size.

The Triumph petite bras collection is specifically designed for the smaller proportion figure type – maximizing the petite shape.

7. Bikini tops for small busts

You may want to wear a bikini top with no padding at all. Or maybe you want the opposite and create the maximum cleavage with a push-up gel bikini top.

See my selection of 5 bikini styles for the smaller busts.

8. Plunge bras for low-cut tops

A plunge bra is a must-have bra for lower necklines. Why not make it one of your favorite feminine bras?

I think this style of bra is very sexy on smaller busts. See 10 plunge bras

9. Starter sports bras for girls

These 10 starter bras for girls are all designed for developing bodies.

10. Tops with built-in bras

A top with a built-in shelf bra is a great alternative to your regular bra. See my selection of 9 tops with built-in bras

11. Girls’ strapless bras

The strapless bra top is a great style to introduce to young girls. No hooks, just simply slip them on.

Older girls like them to wear with any summer outfit. See 6 bandeau teen bras (ages 8 up to 18).

12. Dance bras for ballet, Zumba, and more…

Different dances ask for different bras. Some dances do not require high-impact support while others can’t be done without one. See 10 different dance bras
