Agree with the others--fitting a 38 will largely be dependent on 1) the brake clearance and 2) actual size of the mounted tire.
Realistically, there isn't THAT much difference between a 35 and a 38 and if you need more tire than that, you're probably at or exceeding the limits of what the frame should be doing.
