Musical guest The Knocks from NYC will be spinning a shades of summer (get it?) playlist and a special Guess photo booth will be on site, where you can try on different summer shades. After all, you want to make sure you look good in those snaps before getting tagged on Facebook. And, because Guess is feeling extra generous (and they love our Refinery29 readers like you), they are giving away 10 pairs of sunnies!
All you have to do is "like" this post on Facebook and leave a comment with the Lolla act you are going totally nuts for this year, and you'll be instantly submitted for a chance to win a pair of Doreen (pictured) shades. You have up until the end of the weekend to enter! Winners will be contacted on Monday, August 6. Good luck!
When: August 2, from 6 to 8 p.m.
Where: Guess, 605 N. Michigan Avenue #2 (at E. Ohio Street); 312-440-9665.
