Crochet to Go

These Chanel-inspired baby sweaters are so cute I'm angry I didn't think of them first. I think it might be my next project. I want to get the shape and pattern exactly right. Houndstooth, maybe? This picture is a knockoff, but it's close to what I'd like to do. Pink and black is definitely the way to go--I think it just needs a border and some big buttons.
