Hello and welcome! I play five characters, and two Spades.

[starscrownher] Urania Apollonides, Six of Spades: He likely knows her as that woman who possibly actually thought she was a Greek muse. She's kind of stopped that, though. I don't know if Charlie does women's tailoring too, if so Urania might take things for alterations.

[headfollowheart] Zoe Kattalakis, Four of Spades: Depending on how long Charlie's been gone, it's entirely likely that Zoe was a Heart when he left. She challenged across as a Four in late January. She also dates Victor, so if Charlie makes/alters Victor's suits, they might know of each other that way - but then again, it's just as likely they don't, so it's up to you.

[heartsthespades] Jordan Novak, Nine of Hearts: Born a Spade like his younger brother, he switched to the Hearts at thirteen, but he still has a lot of friends in the Spades. He's also a fan of fine tailoring, so I'd be willing for him to be one of Charlie's clients.

[uncutclarity] Avery Hamilton, Jack of Diamonds: Has a penchant for sleeping with Spades, so Charlie might see her in and around the Castle - but it's unlikely they know each other beyond that.

[cipherspeak] Elisha Kagan, Ten of Clubs: Elisha is the Clubs' resident closet Spade spymaster and friends with a few actual Spades (and frenemies with the Jack). He knows of everyone Charlie, so he knows of you. :D He does tend to dress more casually, but he owns Savile Row suits for necessary occasions. However, he probably uses a Club tailor for them.

Welcome!
