I hardly ever shop factory stuff and just prefer to get the real thing on sale, but curious about how JCrew's factory line stands up to the retail brand? Do the sizing/fits align? My wife has bought a few items from factory, and it seems like the styles are similar but the fabrics are a step lower. Is this about right? Are there any factory items that are pretty comparable to the retail line? I could image that button downs might be quite similar. Thanks!
