AD&D (1e) states that thieves can only wear leather armour.
Does this include studded leather? I've always played not as I can't think of any instances where studded leather is expressly included as allowed in descriptions, however coming back to the game I'm not sure this isn't just an assumption I've made and that it could be fine.
So can thieves wear studded leather? And can you cite where it says it's OK?
(I believe Unearthed Arcarna lists penalties for armour other than leather and lists studded leather, padded armour and elfin chain as valid for thieves (but nothing else) but I've always seen the later hardbacks (everything after D&D-Gs) as AD&D 1.1 so I'm kind of looking for earlier citations).
