I love the one you just bought, just be careful with the leather trim (mine got dirty, I have the white MC). I'm currently using the suhali zipped compact - still getting used to it...
I have a Monogram Porte-Tesor International and I adore it. I used to have it in MC also, but sold it because the vachetta on the sides drove me nuts. They would get dirty so easily! I still love the MC wallets though ... or anything MC really.
I use the mono ludlow. Looking into a new one, but (kinda have to wait awhile...) ...but the vernis french purse in fuchsia is a definite contender (to go with my baggy gm), or the porte tresor international in mono/MC...not sure which.
Right now I'm using a MC cles and a mono cles clipped together. I think I'll be buying either the koala or the french wallet in white MC eventually, just have to work up the courage !
