jesus christ, old navy is fine if you are an 8 year old girl.
anyway, i prefer my jeans to be form-fitting, as i have a stupendously good ass and the chicks love it. therefore, i wear french connection, energie, and diesel to name a few. they will cost you $100+ but they feel great and look great and are definitely worth the investment.
Old Navy are probably worse quality than wal mart brands and so on. They shrink, fuck up, fit so badly that it isn't even worth the 20 bucks they cost.
