I have two Lanvin bags, both of which I purchased at Barney's. I like them because they seem a little bit edgier than my other bags. One is the black Kanvas with the chain handle. It is slightly heavy, but not bad. It is really a great bag for every day. Holds a lot and easy to get in and out of. Totally durable.
You don't have to undo the clasp which I find their clasps annoying . . altho I do have the clasp on other my Lanvin which is the cushion crushed patent hero style in the cobalt'ultramarine blue. That one has the fabric handle so I can use that on the other bag if I don't want to deal with the chain. And without the shoulder straps they are great too. The handles are perfect length to go under your arm . . . Whenever I see people carrying the hero bags around they are unclapsed

but they are under the arm
I am a huge Lanvin ballet flat person so I got into the bags because of the shoes . . . my cobalt blue crushed patents are my fave ballet flats. I don't think are made as well as some bags - LV or BV . . . but definitely comparable to Chloe to me . . .
