Wow, not a Mass Effect fan but those are really nice. I could tell what characters they relate to, for most of them, and that's with my extremely limited knowledge of the series. Really well done. *u* They're going to be hella expensive though, hah.
Torn between Kal'Regger, Mordin, Liara and Thane (reminds me of Tron). I'd also love Kasumi's a bit more if it were in red.
Kasumi's hoodie reminds me of the Nightingale armor from Skyrim. I'd definitely get Thane, Mordin, and Legion's.
Liara's hoodie looks like a futuristic Assassin's Creed outfit. I'd go for Kaidan, Wrex and Zaeed ones. Gotta go with my big mens. Though I do like Kal'Reeger and Mordin. You just want one in pink, right?
