so there are 10 costume slots. i have unlocked 9 of them. i am lvl 50+35 veteran, and i have 2 more free tailor sessions, but no more unlocked slots, how do i unlock that last (10th) slot? i have done the tailor missions for the first 3 tailors, the only ones i know of. i don't understand how any of the other ones have unlocked quite honestly. i just want to be able to use my free tailor session on the 10th slot but i don't know how to open it. can anyone tell me? thanks
and sorry if this is not the way to ask this question, but again i don't know how this works.
