First, the stores at the outlet you are looking at shopping at are more high end than most outlets. There is an outlet like that an hour away from me, but I haven't checked it out yet. This is just about the outlets I shop at.
Maybe it is because I wear plus sizes but I often have better luck at them.
I have been in Nordstrom and heard SA's discussing pulling items to be "Racked". I asked, and they said that the items were going straight to Nordstrom Rack. Straight from the store. I have found items that I purchased for full price at Nordstroms at the Rack.
At the rack I often find something fab that is marked $500+ I have no idea if they really were $1000+ and in the store to start.
However, I find very little here, and a lot of the items seem quite low level. Much lower than at the Talbots outlet, for example. There are often nice shoes, but never what I need in my size.
At the Talbots outlet I find both outlet specific and from the store clothing. I find the quality to be similar to the stores, and I purchase mostly here.
The Eileen Fisher outlet has clearly delineated sections, if you ask. Regular, full price current items, items that were excellent sellers in the past and were brought back for the outlet, and clearance items. I don't know if the clearance items are from all areas or not. Then during the year there are further sales and sample sales. I have found some wonderful things here. A long wool open topper in an interesting variegated gray for under $150. A marbled black and white sweater for under $50.
At the rack I often find something fab that is marked $500+ I have no idea if they really were $1000+ and in the store to start.
At Saks I bought an expensive crystal liquid soap dispenser and soap dish. Elegant splurge, and I had no idea how much better it would work. It gets every drop out of the liquid soap. Also a beautiful pair of cashmere gloves.
I imagine that what everyone said previously is true. I just wanted to add my experience.
