Size up! Usually a size XS but will often choose a size S in sport bras sense I don’t like them to be to tight. In this model I wear a size M to be comfortable. Otherwise very nice design and quality.
The bra is really cute. The shape of the cup pads are odd but I find them to be very flattering. The logo shown in the photo is not present on the bra. I wear a 32G and I’m happy with this as a medium support bra.
