Freya is my favorite brand for bras and bathing suits. The size is consistent, and they last! This top has a single clasp in the back, so if your band size is snug, bump it up to the next size. This is quality material, lined, and definitely not see through when wet. You pay a little more with Freya, but their products last. one more note: Freya is a British brand and their sizing is in British bra sizes.
