This sweatshirt is super easy to use. Just slip it on over your bikini when you're at the beach and feeling a bit cold. You can also wear it casually on other days. When it comes to washing, use a gentle cycle with cold water to keep the color and fabric in good condition. Avoid using bleach as it might damage the cotton. Hang it to dry instead of putting it in the dryer to prevent shrinking. With proper care, this sweatshirt will stay soft and comfortable for a long time.
