Bracelets
Lady Knight Alanna of Trebond and Pirate's Swoop couldn't wear bracelets. She had no problem with other types of jewelry- even earbobs, now that her ears were already pierced- and while she hated dressing up, well what reasonable person didn't?
But never bracelets.
Her friends hadn't bought her another after she'd thrown George's clear across the room (and she hadn't even been mad at him that time). She'd tried- really had- but she just couldn't take the sensation any longer. She still swore it wasn't because it was from George.
No, Alanna hated bracelets because they reminded her of shackles.
