I need a tiny wallet that could fit in my Chanel mini flap bag. Ideally, I would love to carry a mini pochette, small wallet, keys, and phone in my chanel mini. I currently use a zippy compact wallet, but it takes up a lot of space. I love the zippy coin purse style, but it may be redundant since I already have the zippy compact wallet. Also, the Rosalie is sooo cute, but I can't compare them in store since it is always sold out. Is the Rosalie thinner than the Zippy coin purse? Which do you prefer and why? Thanks!
