HOW TO MEASURE BRA SIZE

DETERMINE BAND SIZE

The first step is to find your band size. This is the measurement around your ribcage, just below your bust. To get an accurate measurement, wrap the tape measure snugly around your body, making sure that it is parallel to the ground. This will give you the number that you need to determine your band size, which is an essential component of finding a bra that fits well and provides the support you need.

Once you have determined your band size, the next step is to find your cup size. This measurement is taken around the fullest part of your bust. Once you have this measurement, subtract your band size from it to find the difference. This difference will correspond to a letter, which is your cup size. Reference our bra size conversion chart below to see which cup size matches your number.

Check that the band doesn't hike up or shift in place. Move your arms to see if the band moves as you move, which indicates that it's too loose. The cup should contour over your bust without gaps or spillage. If there's a gap, the cup is too big; if there's spillage, it's too small. The center point of the bra should sit flush against your body, and the underwire should lay flat without digging in.

A proper fit, the band should be snug against your ribcage and sit parallel to the ground.

The shelf life of bras are typically 6-8 months with regular wear. It is recommended having 3 bras to cycle throughout the week to help your bras last longer. We call this "Wear One, Wash One, Rest One."
