Sofia Vergara can wear a burlap sack for Halloween and still manage to look sexy ... but here she is giving us a special treat in a form-fitting costume that shows off her voluptuous Latina curves.

The actress, 38, posted this photo on her Twitter account while taping the Halloween episode for her hit show Modern Family. Her TV son, Rico Rodriguez, looks adorable as a little Frankenstein!

So is the Colombian beauty a sexy witch ... or a feathery saloon girl? Whichever it is, Sofia looks muy caliente!
