Too funny. I own two pairs of jeans that are comfortable and I alternate between the two. Sarah has a closet full of clothes and she is already whining about not having anything for school. This child is going to fit perfectly in a sorority someday. 
I have three pairs of Levi’s that I alternate between – one really faded pair and two that are the same shade of a darker blue.
I can relate to your daughter. I get bored with my clothes pretty quickly and always feel like I need more more more. I thought I’d get past this as I got older, but I’m 35 and still just as bad as ever about it.
