In college I actually did the whole spring break in Mexico thing, and I came back with three or four versions of this dress.
Here's another great, authentic-feeling option.
Pricey, but perhaps worth all the double takes.
Also a perk on beach days, when you'll easily be able to spot your clothes in the sand post-swim.
The oversize off-shoulder tier just needs a pair of earrings and some flat leather sandals.
You can't make this stuff up.
A good voluminous top to offset very teeny denim cutoffs.
In case longer dresses are more your thing.
The pom pom trim makes them more festive.
Since it's still cold in some parts of this country, even though it's May.
