One thing I find very different from Chanel is the logo situation ... it's generally plastered on all things Chanel, and it's very subtle here. The logo coin is detachable, and otherwise the bags are unlogoed except for the lining. When I had my Happy I kept the coin on ... I find it a beautiful logo, and not once was it recognized.
Those bags are a little bit chanel-ish, Lanvin is a pretty good brand but they fail to transmit the Lanvin spirit into their bag imo
