Show off your style with 'Thirteen', a trendy sweatshirt from Hypertwenty. It's a must - have for fashion lovers.

To wear this sweatshirt, simply put it on over your head. You can pair it with jeans or shorts for a casual look. When washing, turn it inside out and use a gentle cycle with cold water to keep the colors bright. Avoid using bleach. Hang it to dry to prevent shrinking. And if it gets wrinkled, you can iron it on a low - heat setting.
