Gentleman's Gazette/Fort Belvedere is a nice source for hard-to-find fancy menswear accessories from a beloved YouTuber. The e-commerce and delivery experience was solid and industry-standard, and the quality of the products were pretty good. It's really expensive for the merely good Vietnamese garment production on offer, but in many cases GG/FB seems to be the only online way to get "correct" things like evening wear accessories in just-so materials. I suspect that actual old-money guys would have a family hookup to obscure sources for such accessories. I like how Fort Belvedere democratizes dressing well at higher levels of formality.
