Ariel Winter -- Hangin' Out At Coachella (PHOTOS)

Ariel Winter got right into the Coachella spirit ... combining some lace and ripped shorts for a barely-there outfit.

Winter was spotted strolling through the Californian festival grounds Friday with boyfriend Laurent Claude Gaudette.

We can't speak for Gaudette ... but we're guessing he'd give his gf two big thumbs up.
