Get to know your breasts. The size and shape of your breasts may impact your bra size and influence which style is most flattering to your body. Breasts and bodies come in every shape and size. Instead of worrying that your breasts don't look like a Victoria Secret Model's, concentrate on dressing for your body and finding what looks best on you.

Examine detailed fitting guides that recommend bras for many different shapes and types of breasts. They make suggestions for women with prominent breast bones, large areolas, distended stomachs, and more.

Consider the function of the bra you are buying. Is this an everyday bra to wear under a t-shirt? Do you wear a lot of low-cut shirts or are you planning to wear a backless dress? Maybe you can only afford one bra and need something with versatility? There are tons of possibilities for different styles, cuts, and fits.

Check out a guide to the pros and cons of different bra styles, and on which bodies and breast shapes they work best.

A seamless bra can be a great everyday bra to wear under T-shirt or with other form-fitting clothes, as it will be almost invisible underneath.

Buy a sports bra for exercising. If your breasts bounce or move too much during activity, the supportive ligaments begin to break down.  Bouncing can also become very painful, and the discomfort may eventually prevent you from participating in activities.

Check the impact or intensity level when shopping for a sports bra. A low-impact bra works great for yoga or hiking. A high-impact bra is necessary for activities like running.

Smaller-breasted women are usually comfortable in compression bras (that give the appearance of a "unibreast") and look like a cropped tank top.

For larger-breasted women, a bra that cups and encapsulates each breast may be more comfortable and inhibit bouncing. These bras have wide straps and clasps.

You may also find a bra that combines compression and encapsulation, which will give you the best support overall.
