Well, I owe my vintage Chanel collection to
eBay Seller: mimiaction: Clothing, Shoes Accessories, Jewelry Watches items on eBay.com.
I adore her, she sells amazing items, hard to find items, and there is always room for negotiation.
But, that being said, always, always, always get things authenticated before you purchase. Even though I adore her, I still get everything authenticated first. It's nothing personal, it's just being careful.
