Upclosenstylish has a twitter account that states what she is wearing. It is very possible she is paid to model the clothes/accessories for the brands. Social media is a really cheap way to advertise.... Just a thought....
I thought that. I thought maybe she owns a boutique like Intermix or Browns. The type of boutique that sells a mix of high and mid range but then she would say something along the lines of 'I'm wearing J Brand jeans, picked them up at Intermix Madison Ave'.
Or maybe she has a stylist friend who tries looks out on her. I used to do that on my sisters.
Ok, I'm grasping at straws here, I think everything she wears belongs to her.
