For more details on measuring your underbust and overbust, read below.

Measuring Your Underbust

Stand straight with your arms hanging casually by your side; if you can get a friend to measure you around your chest, directly under your bust.

Ideally, measure yourself while you are wearing a good fitting bra.

The tape should sit directly under your breasts (where your bra band would normally sit), should be horizontal all the way around and be as tight as possible without being uncomfortable (exactly like your bra’s underband).

This measurement is your Underbust.

Measuring Your Overbust

Still standing straight measure horizontally around the fullest part of your bust (usually over the nipples). This is best done while you’re wearing a good fitting bra.

The tape should not be to tight resting lightly on your body. Make sure the tape is straight across your back and is parallel to the floor.

This measurement is your Overbust.

Crop Tops

Crop tops can fit differently from cupped bras. Generally speaking they are more similar to women’s clothing sizes.

XS = 8 S = 10 M = 12 L = 14 XL = 16 XXL = 18

Sports Bras Direct recommends crop tops for cup sizes A-D only. You must also check that the specific style of crop top suits the level of impact you require. Breasts bigger than a D cup require more specific support from a cup-size sports bra.

Each Brand has slightly different actual measurement guidelines for crop tops. Please check the brand-specific sizing below to establish the best size crop for you.
