Using this top is super easy. Just slip it on over your head and adjust the lace - up part to your liking. When it comes to maintenance, it's best to machine wash it in cold water with like colors. Avoid using bleach as it might damage the printing. Hang it to dry to keep its shape. As for sizing, refer to the size chart carefully to pick the right one for you. Also, if you want to make it last longer, don't iron it directly on the printed area. Enjoy wearing this trendy top!
