Help! Baggy pedal pushers!


  

Hello retro sewers, I need your advice! Has anyone sewn these pedal pushers or a similar vintage pattern? I've taken mine in quite a bit to avoid the balloon trousers look, but while the front view is fine, the backs of the legs have gone all wrinkly. I don't want to make them too tight as they'll look a bit rude, but would like them to be a bit more defined. Any tips on making the fit better? Am I messing about too much with what should be a loose fitting pattern? Have I gone for the wrong fabric (denim)? Should I just give up and start again in a softer fabric? Help!
