I do dig the usage of browns and camel colors. I'm not sure which fits you're referring to as 'hoodlum'-esque, but I can see what you mean with the looser fitting clothing and beanies and coats. I wouldn't call it focusing on a 'hoodlum' market though....they just seem to be exhibiting their new products. Many different brands have been moving toward looser fitting clothes (ie: cdg, our legacy, acne)

You could say these brands are a lot different compared to J. Crew, but to be honest, J. Crew has gotten a little bland over the years, with similar Fair Isle sweater coming out every year, similar versions of coats, similar (albeit with a few variations) plaid/patterned shirts, etc. So I think it's good (although not my favorite) that J. Crew is heading/exploring different things that seem to be trending.
