The round sunglasses that rachel zoe wears are so fashionable and cool at the appearance. If you want to buy such kind of round sunglasses, you could go to the online store to have a search. The amazon and ebay have a lot of sunglasses with different styles. You could go and search the round sunglasses.
OK, it seems that you are very interested in the type of sunglasses that rachel zoe chooses. Anyway ,as a clothes designer in America, she likes to wear sunglasses in public. And those round sunglasses are quite compatible with females, also you could get those round sunglasses at Walmart vision center,where there would be lots of options for you, and the prices could be affordable. Also, some online stores mighe be more attractive.
Definitely I have noticed the classical round sunglasses she wears. Sunglasses with perfectly circular lenses have been a huge trend since the beginning of summer 2009. Rachel actually makes the circle sunglasses look pretty amazing and now.
I know two brands offered this typical sunglasses,Lanvin Wouters and Proenza Schouler. Lanvin Wouters Sunglasses cost almost $300, Proenza Schouler round sunglasses are nearly the same with the price of $310.
You can buy them in the real store, or you can buy them online. I think online shopping may be more convenient.
