Sorry, I think J.Crew is crap. Too many times have I bought their clothes and found them turn to rags after a few washes. Very disappointed with the quality, considering the price.
BR is much better than J.Crew, even though their prices are a bit out of whack, too.
In terms of durability, I've had most success with "mainline" apparel. Abercrmobie, especially, seems to make indestructible clothes.
