It's BETSEY-ESQUE. It can also be spelled Betseyesque, but I think Betsey-esque is more pleasing aesthetically.
Definition: (adj.) An item (particularly clothing) that "looks" youthful, vintage, over-the-top, and FUN!!
Usage: This top is SO Betsey-esque :)
Take a look at this top; I totally love it!

I really hope it doesnt make me look preggo, though. :-/
