The general rule of thumb that you can use to convert a man's size t-shirt into the equivalent of a woman's size t-shirt is that a man's t-shirt is generally two sizes bigger than a woman's. So, a medium man's t-shirt is equal to a woman's extra large or XL t-shirt.
UK size 11 equals European size 45.
