Welcome to the forum. I can't really give you an equivalent t-shirt size for bike jerseys. The reason is that bike jersey fits seem to vary a lot. some are made to be more "casual" and thus, fit less snugly. These are often labeled "club" fit I believe. Others are made for a very form fitting fit and these are often labeled "pro" or some such. And lastly, I find that it varies by manufacturer but for me, specifically if they have a European fit. If so, then, for me, I find I have to size up.

Anyway, the jersey is sold and on its way. If you need helpful info on jersey sizing, I'd look thru the forum's Gear and Accessories area to ask for or search for helpful information from forumites. Also, the sponsor of this forum, team estrogen, is most helpful with helping folks with gear and advice. Give 'em a call.
