Medium Black caviar classic and a black mini in lambskin.
If you are able to buy both then I would say get the small and go on the wish list for a mini. I imagine minis will be harder and harder to find as the price of the classic goes up as so many people think its either not worth it or have been priced out so opt for a mini instead.
Do you mind me asking what are your reasons for wanting each bag? If the mini is because of the better price then i suggest going for the small as you’ll only wish you got it later down the line!
If your only getting the small because the mini is hard to find I would wait and hunt it down.
I also think its a misconception that caviar is more durable it just depends on what you are willing to accept as wear and tear. Lambskin will scratch easier but i hate the look of worn off corners on caviar! I've even seen it peeling
I always think vintage lambskin is beautiful but who am I to talk as I didn't dare get my classic in lambskin
I have both mine with gold hardware but I've seen people say silver looks better for longer as the gold will eventually show the silver underneath. this hasn't happened to any of mine yet so can't comment on how long that would take to happen and chanel can always change the hardware for you.
listen to your heart and try not to get to caught up in our opinions because everyones lifestyle is different
