I disagree with you on the above post. N&F's construction quality has improved noticeably in the past year, but I think it is still far behind Momotaro and a little bit behind 3sixteen. I would also say that the construction quality is around the level of APC now, where it was actually worse than APC up until the past year IME.
I like that N&F is able to offer exotic denims at affordable prices, but unless they are on sale, I don't find them underpriced, especially the standard models. I think that at retail, they are pretty much priced where they should be at.
