- FOOT: We start with the true foot, which means we measure from heel to toe. That measurement (in centimeters) is then translated into our standard sizes.
- To find your foot measurement closely trace your entire foot onto a piece of paper and measure from heel to toe. If your measurement is between chart numbers, we recommend sizing up. Be sure you’re putting your full weight on your foot while tracing. Please note: for the best results, measuring later in the day is recommended.
- We created this easy-to-use sizing chart so that finding the right size shoes for your kids won’t be a workout in itself. *Due to the metric/imperial conversions, there will be some instances where two US sizes will equal one UK size or one CM size.

- Not sure how to find your bra size? Take our fit tutorial to find the correct size for you.
- BAND SIZE: Standing straight up with an unpadded bra on, measure closely around the chest just under your arms, right above the bust. If your result is a fraction, round to the nearest whole number. (ex. 33.7” rounded to the nearest whole number, your band measurement is 34”)
- BUST SIZE: While wearing an unpadded bra, loosely measure around the fullest part of your bust. Round to the nearest whole number. (ex. 34.5” rounded up to the nearest whole number, your bust size is 35”)
- CUP SIZE: While wearing a non-padded bra, keep the tape parallel and measure at the fullest part of your bust. Round this measurement UP the nearest WHOLE number. Subtract BAND size from BUST size to find your CUP size. EX. 36” - 34” = 2” = B = 34B
