So the clothing on the models is a few sizes above? That's good then, they probably are well cut -it is RAF.
its me in the clothes btw, i like them a bit on the loose side. The jeans are perfect, narrow leg, but easy/comfortable around the crotch and seat. Extra long leg. And i found that some of the styles esp knits are intended to be fitted and others baggy, going by the fact that i tried on M's. Some were super fitted and others hung loose and long. I think it is a signature thing for Raf, the play on proportion.
