I've done quite a few variation of searches and I can't seem to find this information. Was it introduced in Pre-Spring of 2005? The only reason I think it started is just by going into the Reference Library and looking at colours by season and I see no days in F/W 2004 but I start seeing days in Pre-Spring 2005 but I'm not sure whether it's just cuz no pictures of days were posted in the F/W 2004 thread or whether they just plain didn't exist back then. If anyone knows and could reply to this that'd be great! Thanks!
