>>18479939 (OP)go custom made
get a psychedelic shirt (with convertible cuffs), high-buttoning vest, and a frock coat
honestly depps wonka had one zillion times more style than wilder
wilders costume reeks of tacky 70s novelty wedding attire
depps costume has a very bauhaus, mod sensibility to it that makes it simultaneously slick and futuristic but also timeless
its whimsicality is baked into every detail, making it richer and subtler than an obnoxious purple coat and flouncy bow-cravat
look into mod and peacock fashion of the 60s, anything "atomic age", styles from the edwardian period, designers like heidi slimane, karl lagerfeld, SLP
go for brands like topman for vests and pants, modshopping for shirts, jeffery west for boots, and of course, a frock coat is gonna have to be vintage or custom (not to say ebay doesn't have some good ex-rental frock coats)
learn a bit of DIY to make some candy-themed accessories and jewelry, if thats what you're about
don't forget the purple nitrile gloves
>>18480916loser doesn't realize we live in the post-cringe, post-retro, post-post-modern era of fashion and aesthetics
all of history's aesthetics are at our disposal and experimentation and authenticity is lauded over conformity and irony
but yes, do commit to the bit, groom yourself well, don't half ass it with jeans and a graphic tee
