I'm sure that varies. Also I'm 99% sure that Yohji its arriving in Paris with boxes and boxes and boxes of garments. Usually couple of days before the show its the pre-styling where you have one model for whole day and you building looks with the garments you have around you according to your concept. After that you have casting where you have 3-4 important and different outfits, which goes on the models that are coming to be seen. After long day and seeing hundreds of models you edit the one you like and you call their agency so they can come next day for actual fitting of the look certain boy will have. You may add looks (garments) on the way depending how the line-up its.
Then the day of the show you have all the buyers coming to look at the full collection and they are picking up things, which means they might like something not on the runway.
That's what I've seen from my couple season in Italian knit house. Of course different brands have different scheme of doing things, but it won't be far off.
That makes things a lot clearer. Good to get an insider's insight. Thanks.
