If X likes to steer her bike with her thighs on the bike nose, she might prefer a B17 rather than a B17 Short. ("s" is for "short")

If she rides in skorts, she might like the B17S more. I ride in skirts, but I prefer to use the nose of the saddle to help me control the bike. And in all honesty, the skirts never catch on the full-length nose of my B67. (now, the back of my capris sometimes snag, but not my skirts. I chalk that up to me just being clumsy.)
