Here's a helpful little hint..
If you aren't looking for the usual bro / Jersey Shore options at Simon's, go up the escalator located near the front of the store. You will soon discover their amazing (and seemingly unknown) collection of very high-end brands, tucked away on this upper level.
Everything from Acne Studios to Kenzo, with plenty of nice pieces in all sizes. Really amazing and a section that you have to know about to find. Well worth a visit.
4 stars because the staff are snooty (in this section) and expect you to drop 1k per visit to be worth their time.
