Sports bras offer three different levels of support: low, medium, and high impact. The type you need depends on your cup size and the type of exercise you do.
Low impact activities: Walking, yoga, strength training.
Medium impact activities: Dancing, skiing, cycling.
Construction: Low-medium impact sports bras typically feature a cup-less design and restrict movement by compressing the breasts tightly against the chest wall.

Even once you have you have your measurements, finding the right sports bra can be tricky and usually requires you to try a few different sizes and brands. Here are some tips for getting the perfect fit…
Snug, but not too tight: A sports bra should fit tighter than a regular bra but shouldn’t restrict breathing; you should be able to fit two fingers between the straps and your shoulders.
Wrinkles are bad: The fabric of the cup should be smooth. Wrinkles in the fabric are usually an indication that the cup is too big. Conversely, if you’re spilling out of the cup, it’s too small.
Watch out for gaps: Any underwire should lay flat against the rib case, below your breast tissue, and should not pinch or dig in.
Adjust the straps: Raise your hands up over your head. If the band rides up it’s usually a sign it’s too big, though it is possible that the straps or the back closure may need adjusting.
Move around: Before buying your bra, jump around and swing your arms – (it’s probably best to do this in the changing rooms or somewhere else other people can’t see you). If you experience pain or discomfort, then try another sports bra.
