"Don't just reserve Zimmermann's lace and point d'esprit-paneled swimsuit for the beach - wear it as a bodysuit in the evening with tailoring or jeans."
See its so versatile, that £385 price tag is completely reasonable.
You could look like you've forgotten you top at an evening do, as well as looking like you forgot your cozzie on the beach. (We've all swam in our underwear at some point, haven't we?)
