How Many Bras Should I Own Based On My Cup Size?

If there was only one word to describe your lingerie drawer, would it be “confusing?” If that’s you, we can fix that—and you’re not alone! For many folks, knowing how many bras to own and what styles to have can be mystifying. Some people we talked to said they had about five or six bras in their drawer, while others had up to thirty. But what number is correct?

You're wondering, “How many bras should I own?” Since your everyday bras are the ones you’re most likely to wear, well, every day, you’ll want to have a few on rotation, no matter your cup size or support needs. A good rule of thumb is three everyday bras — think one on your body, one in the drawer ready to wear, and one in the wash. We recommend:

  • Two in a neutral or skin tone shade, like Mocha or Taupe
  • At least one darker color, like Black or Espresso, for outfit variety

Consider adding a wireless option into your rotation for those days when comfort is key and a sports bra for those days when you want to get active.


Small Breast Size vs Large Breast Size

In curating your bra collection make sure to consider several factors, such as your lifestyle, personal preferences, wardrobe situation, and most importantly your breast size.

While breast size doesn't determine how many bras you need, it does determine how much support you need, what functions your bra needs to perform, and how quickly your bras get worn. Understanding your breast size and bra needs will help you determine how many of each bra type you will want in your top drawer.

So, let's explore some of the best bras depending on size so that you can better determine which silhouettes you want to invest in.


Must-Have Bras for Small Breast Sizes

Those that are petite can easily enjoy the freedom and comfort of wearing wireless bras, plunge bras, or even going braless. However, there are some essential small breast bras that you should have in your collection. Here are some of our recommendations when it comes to small breasts:

Mix Up Your Bra Drawer With Flirty or Bold Styles

We all need to cover the basics, but what about a bra for those days (or nights) that require a little something “extra?” Consider adding one or two statement bras to your collection. Whether it’s a hint of lace, a sexy plunge style, an alluring balconette bra, or even one of your everyday bra options in a bold new hue, a statement-making piece is every girl’s best friend. You could even pop it under a sheer blouse to really let it be the star; we won’t stop you! Here are some of our recommendations.


Lace Contour Plunge Bra

This bra is a sight to behold. It’s particularly is a great bra for those with large breasts as it has wide, lace straps that help provide support and redistribute weight. Show off some cleavage with its plunge neckline style, and add some spice to your look with its  intricate lace. 


Lace Balconette Bra

This lace balconette is a beautiful choice for petite women who want to channel their inner vixen. It has a balconette neckline that lifts and separates your breasts and an all-around lace overlay that creates a stunning effect.


Bras for Tricky Tops, Dresses & Button-Downs

It’s also important to have a few bras for special occasions and tricker tops and dresses—like strapless bras, one-shoulder bras, or spaghetti strap styles. Multiway or convertible bras are a great choice, as these can be worn several different ways. It’s a good idea to have at least 2 of these bras in rotation as well.


24/7® Classic Strapless Bra

This is a great convertible option since it comes with two sets of add-on straps, one tonal and one clear, to do double duty. Straps can also be worn five ways—strapless, halter, one-shoulder, straight, or crossed in the back—to provide maximum style versatility

If you find yourself searching “buttondown shirts for large busts,” we may have a bra solution for you. You can close the button gap in those “almost-just-right” shirts with the right minimizer bra. Minimizer bras can reduce the projection of bust, completely changing how your clothes fit. This one not only reduces busts up to 2 inches, it is also soft, breathable, and can be worn x-back. We even have a wireless minimizer for all wire-free lovers. It just might be a sundress summer for you after all!


How to Care for Your Bras

Once you have your bra staples handled, it’s important to take care of them to help extend their longevity. This means storing and packing them properly and hand-washing them when you can (we know it may not sound like the most convenient effort, but it’s worth the effort—we promise!).

Depending on how often you wear your bras and how many are in your total rotation, you may consider giving it a wash every 1-2 weeks, more often if needed. Bras also need rest days between wears, so having a few alternates is always a good idea so you’re never caught without.

Many women are surprised to learn that even their most-loved bras have about a one-year lifespan. In addition to more obvious signs of wear and tear like loose threads, you’ll also know it’s time to replace your bra when you notice a change in comfort and feel. For example, if your straps are stretched to the point of no return or your band still feels too loose on the tightest hook, it’s probably time to say goodbye. Most importantly, if your bra is no longer doing its job is keeping you comfortable and supported, there’s no point in holding onto it.
