After you’ve chosen the perfect dresser, the question remains: mirror or no mirror? If you’re a fan of the former, just be sure to take measurements beforehand – if a mirror is wider than the dresser, it might throw off the balance of your bedroom. Luckily, this 38.18'' H x 38.18'' W piece mounts to a compatible dresser (which is sold separately), so you know you're getting just the right size.
