As long as your daughter is ok with it and you take good care of them. I never had to worry about this with my mom because my mom is very much overweight...I could fit like...5 of me, in one of her shirts, so there was no way she'd ever had borrowed some of my stuff. I don't think I'd ever use any of Nina's stuff, though...and not just because she's so little right now!
I have my own style. My clothes are my clothes and her clothes are her clothes.
