Loveternal Unisex T-Shirt 3D Printed Casual Graphic Short Sleeve Tops Tees S-3XL

Can the tshirt be washed in a normal washer machine?

I want to order the woman’s bra one for a woman, she’s a size 16. What size should I order (getting confused between the men & women’s size chart)

Is the back plain or does it have back detail?
