I made a comment in a thread yesterday with this link, but thought it might be helpful for anyone that wants authentic world tour kit both used and unused.
I am not affiliated with this store in any way, but was able to tour their office / warehouse a few weeks ago. They have bins and racks full of various team issued kits. Both directly from the teams and riders. I lot of it is surplus, but you can also find actual stage/event used kit bought directly from riders.
Gloves, arm warmers, leg warmers, bibs, helmets, skinsuits, really anything. Even components from their bikes.
Before you hit eBay, have a look at this store.
They’re based in Girona.
