Ash Costello’s ripped sweater dress is actually a “Miss Krueger” Halloween Costume ($35.20), inspired by the red and green striped sweater that Freddy Krueger wore in the film A Nightmare on Elm Street. This is older photo, but not being a horror movie fan myself I didn’t recognize the significance of her sweater at the time.

Sherri DuPree-Bemis looked pretty in pink with this monochrome outfit. Her Forever 21 Alice In Wonderland Tank has a background with purple and pink flowers in many shade that match both her hot pink hair and her rosy pink shorts. I believe her shorts are the BDG 5-Pocket Shorts in Pink from Urban Outfitters ($39.00), though you can find a bunch more options in the widget below.

This outfit which Rihanna wore to a nightclub is a mix of sexiness and “don’t mess with me” attitude. She wore a Sleeveless Denim Jacket from Maison Martin Margiela ($989.00) with a camoflauge hat, leather bralet, and Topshop American flag shorts.

Rihanna’s exact pair of Dark Denim Flag Print Hotpants are sold out, but Topshop have two similar pairs in stock at the moment. You can also get a cheaper pair of flag shorts from PacSun and if you’re feeling creative, you can make your own with some fabric dye and paint.
