Hmm, probably J Crew or Banana Republic. I like their quality and fit.
I am super boring, it would be Old Navy. I buy all my clothes there. They are affordable and cute to me, but yet casual. I wear a uniform to work and I live in jeans and cute tops otherwise and I love that I can afford their clothes.
NY and Company here too.
Or Victoria's Secret. If its a spree and I dont have to be sensible, I'd buy bras and panties for sure. Frivolous ones that dont have to look good under white/light shirts.
I love Anthropologie! Unfortunately, I haven't had great luck with the fit of the clothes at Modcloth, I seem to be too tall for many of their items (the arms are too short, the waists are to high), which is too bad since they have such stylish clothes.
