Personal choice, of course but the current tops are definitely men's. Look at the size guide on the ccfc store and you'll see. Men's cut is definitely different. Try on a large shirt in a woman's size if you want to see the difference. Some women don't mind wearing men's clothes but I think a choice is important.
The merchandise in ccfc store often has more stuff for infant and baby girls than for women. If that's based on customer research fair enough but it always looks like stuff men might want to buy for their daughters rather than what women would buy for themselves.
