I've been going back and forth between the mono and damier speedy 30, for my first purchase. in the beginning I was all for the mono (it just made my skip a beat when i tried it!) then for the last 2 weeks I was quite set on the damier for the practical reasons (vachetta) and because it's more subtle... ...i've now been thinking about the mono again. However, if I'm spending so much on a purse I want to wear it on a daily basis. So my question is, if I were to use the mono on a daily basis how long would it take before the vachetta started to really show? not the pretty vachetta, but when it gets to the darker brown/well-loved stage. Mind you, i'd mainly be carrying it on my arm, maybe 1/4 of the time in my hand, and I don't lather on tons of lotion, nor do my palms get super sweaty 90% of the time. Any help would be appreciated - thank you!
