Anne do you mean in terms of style, or in terms of price??
I'm about to hit the hay, but here's some initial thoughts and impressions of the shops there. Maybe I'll be more coherent tomorrow
Ann Taylor = JacquiE (midrange prices, mostly kinda conversative styles but some really nice pieces too. Thats the Ann Taylor Loft I'm speaking of. Didn't go into an actual Ann Taylor store.)
J Crew = Country Road (Weirdly I expected this place to be a dept store rather than a regular store. Mid-highish prices. Again somewhat conservative)
BR = Portmans (midrange prices, lots of work-style clothing with some interesting looks and dresses thrown in)
Club Monaco = Witchery/David Lawrence (Mid-highish prices. Minimalist but still interesting with some lovely pieces there)
Forever 21 = Supre (cheap and fun! Although much less nasty than Supre)
Express = ??? (reasonable prices but not super cheap. Trendy but with lots of basics as well. No immediate Aussie equivalent springs to mind unfortunately as I really quite liked this store!!!)
Boden = didn't see one of these stores
Anthropologie = ?? (mid-high prices for psuedo-boho pieces. Like a Tree of Life mixed with some fancy brand and priced accordingly. Don't think there is a direct Aussie equivalent).
Does that help at all?? I'd love to hear others thoughts on this too!!
