The clothes are great. A little preppy, definitely not suitable for 100% of your wardrobe, but a few items are well worthwhile.
J Crew and SouthPark were made for each other; the store definitely fits the mall. They are both upscale, a little pretentious, but tolerable in moderation. Same goes for the staff here: the first few people helping us were frighteningly helpful and really steered me into the choices I needed to make. Then the next couple were downright pushy. I said I didn't want to buy a suit! Why are you fetching swatches? No! Stop!
Forcible suit-viewing aside, the major downside is the price. They gouge you. No pretense. It's just vicious.
