I only recently discovered Ryan Lo, and I love his work. He reminds me a lot of Meadham Kirchhoff and Louise Grey, in the respect that they like to challenge what is considered tasteful by creating almost gaudy brashy designs. And also the spaced out prom theme looks like it should belong alongside the one Rookie did a while ago. He doesn't have much on his website yet, but you should definitely check him out.
Ready To Wear Spring 2013 collection by Phillip Lim. Phillip Lim is a designer whose work I always like, but seem to sometimes overlook. The collection is quite grungy, and has the usual dose of plaid and tie dye, but also has quirky detailing like the little gingham deer's on the dress below.
