Good on you, wear what you feel comfortable in.
The topic of sarongs for men comes up frequently for discussion on a certain other forum but lets not go there as this forum is kilt specific.
I'd have to agree the sarong looks less masculine than the kilt but perhaps a warning shot is appropriate here, Rule #9 states that this forum is not the place for the discussion of cross-dressing, so please lets not see this topic degenerate into a discussion as to the masculinity or otherwise of sarong wearing.
