I'm sure if you look on SC you could find an Elvis outfit, perhaps in an unusual size. If not appropriate for work, as you suggest, perhaps keep for weekends?
Sizing might be, for some, you "just know". Not for me, though. I'm clueless. I suspect Mrs Analogue has given me a useful perspective on what suits, whilst we have been in the shop. She let me down once, though, when I bought a PAM 104 that she thought looked great. It did look great, but but not on my puny wrist...
