I dunno, even Galliano seems to be in on the late 50s-early 60s pretty pastel look with the last coture collection... I don't think we've seen the end of this trend.
Personally, I like this collection. Its very old school June Cleaver pretty.

Yikes.
. especially the latest long evening dresses are to die for. I really love this collection
I actually don't think this looks bad, but I don't understand what most people expect from Michael Kors. His loyal customers will probably eat this up. I thought Michael Kors was always about jet-setting and looking like you're always on vacation and that's what this collection looks like.
