I find the womens jerseys too short too - and I'm short. You might go to your LBS and try mens "race" cut jerseys, they're a more fitted jersey and may work for you. If you like the fit of the jersey and the length, find a seamstress and have her take the elalstic out of the hem and bring in the armholes.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
