look up any word, like fleek:

When you're a cute girl who lives in the south and it's still 90 degrees at night during the summer this is the dress code you should follow. You would benefit from this decision when going out drinking somewhere where you're going to spend time on the patio. A tank top paired with gauze shorts (preferably white) is the perfect example of a slutty casual outfit. Helpful hint - If you wear a pair of heels with it it really classes it up so you can get into the nicer bars & clubs.
Oh no I wish I knew tonight was slutty casual night because now I'm not as hot as all the other girls.

Wow look at that girl! She's so fine in her slutty casual outfit!
