Hey there! Glad you found 2 bags to love! It's a happy dilemma to have! For myself, neither of these bags works...they're just not me. However, out of the two, I'm liking the Chanel bag.
Have you checked the boutiques? Is this a hard to find bag? I'm just not an eBay fan--but, if this is the only way to get the bag of your dreams, then go for it!
