SIZE CONVERSION MADE EASY: Did you know Freya is sold in UK sizing? Please use the size chart to convert your US to UK size. To find your size, measure around the torso underneath the breast tissue to determine your band size. If measurement is an odd number, round up to the following even number. Measure around the fullest part of the bust to determine your bust size. To determine your cup size, subtract your band size from your bust size. Fully cushioned flexi-wire for complete comfort. Super soft spacer molded cups offer a breathable style and a natural rounded shape that is seam-free under clothing. A-frame supports the bust when feeding. Easy access clip adjustment. Toe-back feature to prevent strap slippage.
