Haha, this thread is awesome. I know i work retail so my perception is skewed, but the $50-$100 range is pretty much standard for a tee in this market. We've got National Anthem Tees for $60, W+H for $40-$100, and i'm pretty sure the APC and Our Legacy tees coming for Spring are all over $65.
That being said, the B&N tees are really great. Some of the best fitting options i've ever tried. I'm surprised the brand hasn't gotten more love on here, but it's still a young and relatively small collection. They've got a denim program and made in Italy shoes/sneakers coming next year that i think will go over really well here. I should probably just make a thread...
