My wife is 5.3. She use to wear Warlock Jacket. We both are in-city street riders and don't prefer to put heavy riding suits on weekend rides. Have two brands in mind we usually buy gears and bike stuff from Viking Group's (
Viking Bags,
Viking Cycle) and
First Gear. Have a great experience with them. I'm sure you will find the perfect size there. You can visit them once before going to the famous expensive one.
