I liked Chelsey’s version of the Canadian Tuxedo (denim on denim), but I preferred the top to the pants. It was really nice to see Nancy receiving some praise for her work.
As for Sergio, using fabric leftover from designers is known as using deadstock fabric, not upcycling. There’s no shame in the deadstock game (it’s still a good environmental practice, and it's how I got my hands on some Valentino fabric), but it’s not the same as redesigning an already made garment.
And, I noticed his not so subtle shade of self-taught designers. I’m a teacher, and I have nothing but respect for people who are self taught. They are interested in learning. That’s whats important to me, not how they learned it.
