OK, Molly, we see you! Whether she chooses to wear a bathing suit under this sheer dress or not, the gorgeous pink colour is the perfect item to pack for this Mexican holiday. The lightweight material looks like it is airy enough for some steamy balcony moments between her and Andrew in the tropical weather — even if it doesn't stay on for too long! I could totally see myself wearing this over a bikini with flats or even with wedges at a pool party.
