For handbags and jewelry, I mix high end with low end, from forever 21, asos.com, Tory Burch and Michael Kors. But I would recommend buying from Tory Burch! I just love her designs but then again I love Mr. Kors too! They are both huge role models in my life that I look to for inspiration.
I also love Zara for their amazing shoes, wonderful high heels. I also love Nasty Gal and Love Culture for some nice easy going outfits, but highly favored of course would have to be Asos.com.
