I am currently carrying the Mono Zippy Wallet, it's my fave so far...its very easy to get in and out of and its so roomy! Before that I was used the Mono Porte Tresor International but it was a pain and it didn't hold up very well.
I want a LV wallet in the future...I really want the white mc french purse (I think that's the one). It's about 700 so I may be waiting a while! Right now I am using my new Burberry wallet which I LOVE. I actually like mixing up brands for some reason. I use a Coach agenda - but the bag is ALWAYS LV!!!
I carry the LV card holder - because I have a LOAD of cards (membership cards, store credit cards, you name it). I also use my Small Mono Agenda as a wallet. It holds 6 cards (2 in each card slot) so there is room for my main credit cards and my DL. I like the Agenda because I can keep track of everything in it, its really cute, and I can use it when I don't feel like lugging around my entire purse.
