I'd imagine it's something there or there abouts, not so much the bulk order for us, but that the kits we use aren't actually made in women's fit because Nike don't see it being financially viable, for us, or any club that uses them.
Update: having just checked Nikes catalogue for 2016/7 they...
Stadium shirt rather than a replica shirt, I wonder if they make a women's replica or playing shirt? But also, look at the team, they sell as many shirts a day as the Albion does in a year.
TBF players spec shirts (code 7, Formotion, Techfit and others) are fitted, as are women's football shirts by many of the other manufacturers. Nike don't do them for women, and the Albion don't use Code 7 shirts for the players, but it's not quite right to say football shirts are 'not fitted'...
