I love vintage BV and have had several bags and clutches. Right now I have 5. Just gave one to my granddaughter to play with--she's actually very careful with it.
If they have been stored with care and not misused, they are lovely bags and the leather is like silk. The linings vary a lot--mine are in good condition but I've seen some that are just a mess.
Mostly I have bought medium size woven bags with thin straps that may be tucked inside the bag to transform it into a clutch. I have one that is simply a clutch. 3 are pleated which adds some interest, the rest are simply woven leather with either a zipper top closure or a flap that snaps on the front of the bag. I've sold a few too that I decided I didn't want to keep.
If you look in consignment shops you can feel and examine the bag thoroughly. If you buy online, buy from a trusted seller. I have found that some sellers greatly exaggerate when they say *very good condition* or describing no problems, stains, odors, etc. and you find a stain or tear when you receive it. A trusted seller will make it good somehow if they overlook something, but chances are they will carefully describe the bag.
