We just ordered a batch of jersies for our tandem club. The company that produced them for us (Revi) offers "ladies" and "unisex" jersies. The ladies cut jersies were a little bit shorter, had more relaxed elastic at the bottom, and were pinched in a tiny bit more at the waist. The most noticeable difference is the length.

If I had to guess, I'd say that the ones you pictured were unisex cut.
