Yes, there will be a XS, which corresponds to 14.5 in the shirt sizes. As there are four shirt sizes, (14.5, 15, 15.75, 16.5), there will be four sweater sizes (XS, S, M, L). There will be a dedicated measurement table for the sweaters but for now you can look at the shirt sizing.
I'm afraid not, as it's hard to maintain a lot of different sizes. I assume you've already checked the shirt measurement table for your sleeve length?
