J Crew is a chain store found in most major malls. I used to shop here often but lately I have noticed that the quality of the clothing has gone downhill. Most of the sweaters are either dry clean or hand wash only.
They can be pricey but you can get some decent layering pieces here. Most times I stop in here is to browse. They do offer personal shopping assistance and if they don't have your size or color they will order it for you and ship it to you for free. If you wait long enough then the item you saw a few weeks ago normally will go on sale.
