Would a mens' small fit me?

I am a girl, 15 years old and I want to buy a Guy Harvey T-Shirt online. They have women's sizes but I like the look of the men's better because of the pocket and they also have a lot more designs. I am a women size small in uni T-shirts. So would a men's T-shirt size small fit me? It doesn't have to be fitted or short or anything it can be a little baggy but not TOO baggy.
