These bras are wonderful! Soft and silky. No seams, no wires. Strong lift and support. They mold to your body like a dream. Evelyn Bobbie recently revamped their sizing. The XS on the tag is equivalent to the S on their website. It's the exact same bra. Fits sizes 30C-G, 32C-F and 34C-D. Don't worry if it's tight for the first few wears, it's supposed to be! Ask me questions! Happy to discount for bundles, I have 3 available :)
