This hoodie is dope! The sizing is perfect. It's not too small or too big like china/korea sizing. I'm usually a small, but I ordered a medium to be safe & it's pretty baggy. If you want to wear a think long-sleeve or crewneck to keep you warm, then you should order a size bigger. I ordered a size too big for me, but it looks cute! If you're a girl, you can wear it with leggings and combat boots to look stylish. As for warmth, it's pretty warm for a day that's a bit cold and windy. It's not too thick and it's not too thin. It's safe to say that you can order this hoodie in your usual size. If you want to look fresh and fly, you should order this hoodie!
