Commes de Garcon is a Japanese fashion house headed by Rei Kawakubo and run by her husband. This fashion brand is really a business, with a long list of collaborations and sub-brands (e.g. Play, Black) to help it turn a profit.
As such, we can really expect their seasonal fashion shows to be more show and less wearable fashion. This is their A/W 2015 menswear.
