I haven’t heard of AlexandersKing before seeing this pic, but they seem like a fun, if small, brand! Like the Bruno things I keep reblogging, AlexandersKing is a Mexican brand that mostly sells briefs and jockstraps, though they have some trunks too. The briefs in this pick look like an interesting mesh fabric; the brand also uses a more general fabric, plus a velvet-y looking “prime” fabric. Would be interesting to try out!
