I'll start by just LOVE this brand. The quality and durability of their clothes keeps me coming back, not to mention they are very stylish! I would say the pants fit like loose pants versus tight top and bottom straight pants (if that makes sense). The elastic at the waist helped a lot as my son has a small waist.
