Too short
Size: XX-Large, Color: Black White
Well if your 6ft or taller it's very disappointing it's to short it doesn't fully let down to the waist it feels short your constantly asking yourself can you get away wearing it when you feel a little uncomfortabl. Return it maybe get a bigger size unfortunately for me there's nothing bigger than the 2xl bigger not longer
