These two are from Old Navy. They have a lot of nice cheap ones there. I have both of these. The first in orange and the second in blue. Jem's my twin with the first one in blue!
These two are from gap. I thought all of the polka dots were cute!
This checkered one is from Forever 21. I don't really know how people tie these all triangulary like that. I really should find out. I asked the lady who worked there (I think she thought I was a bit crazy) and she didn't know either so who knows if I'll ever find out.
