Ok fashionistas, do we have to buy shirts/pants/jackets at the sources listed in the welcome package? Or can we find *very* similar looking stuff and get that tailored?

Does anyone makes a fuss if your pants are wool instead of poly, or you find a leather jacket that is close but not exactly the same color/sheen as Perrone's?
(as in: can we get written up?)

I just like my clothes to look like they were made for me, not some hand-me-downs. Don't really care about the garment-based pecking order of who's cool. Thanks!
