Not sure where this fits in, but I think this category is the closest.
Has anyone ever tried wearing cologne or perfume to give off a musky scent, something like what your mandalorian would smell like? like another layer of cosplay.
I found an Etsy store that sells "Cosplay Scents", they have over 100 scents and some are very interesting, in the info for each scent theres a suggestion for cosplay characters that would go good with the scent and lists the different smells that are used in it. Theres a scent called Mercenary that suggests to use it with Boba Fett, Jango Fett, and other Mandalorians.
I'm not sure what the rules are on this sort of thing, but I thought I'd try some and ordered a sample pack to try 3 scents. I'm in no way trying to promote the store or anything, it's just something unique I came across and thought I'd share.
