AG, I'm glad Angie chimed in, because I did wonder a little if you had friend-shopping goggles on. Everything you purchased is fun and casual, but I was wondering if you would really wear it. (Except for the Gap pants, which I think are really nice loungewear, and the ON vest, which seems like a good swap for another spendy piece on which you had doubts.)
I also wonder if you could get a truly nice item for what you spent instead of a bunch of throw-aways. I too suffer from the "ooh shiny ooh it fits" syndrome when shopping so I get the purchase rush, but just because it fits and it's fun is not a reason to give something a permanent home. Or quasi-permanent, since at least for me those items end up being passed along or donated in a few months.
