See the size guides below to help you choose the right size. If you happen to fall between the measurements in the Undies, we usually recommend sizing up for most people. Our fabric is stretchy enough that a bigger size will often still fit, but won’t feel as tight. If you would rather feel snug in your clothes opt for the smaller size. For the other garments, Bralettes, Bike Shorts, Leggings, Camis, you may want to size down for a snugger fit. These garments will offer a little more secure and supportive in a smaller size.
