Irina's is too dark, I'd have to agree with Nina; nobody want's to see all black walking down the runway. I think little pops of color would be good for her collection, maybe colored shoes? That would make a splash...if it hasn't been done before. And the boyfriend shirts are an Okay idea but it they were like "yeah, this was my boyfriends shirt, but I cut it and sewed it and now I look awesome" I think if those shirts had that attitude, they could be great.
I like where Althea's ideas are, but I don't know how well she'll execute them. She seems to be the type that will over work pieces that could have been great it they were simpler.
Carol Hannah's collection is too evening, She said "Evening Flair" but really come on, a little too much.
I'd have to say if I was in favor of one of them, it would be Althea. She has a concept and I'm liking it, now she just needs to pull it together and Make. It. Work.
