Men's Garb to Borrow for 12th Night?

[scotica]

My friend Rob, from London, is visiting and I'm dragging him along to West Kingdom 12th Night, so I need to find him some garb. Does anyone have something I could borrow for him? He's about 5'8", neck size 18, chest 45, waist 40, inseam about 28. Not particular about period or culture (although something that would fit with the name "Robert of London" would be a bonus for me, but he doesn't care!)

Any help greatly appreciated!
