That happened to me too.
Its hard to get balance right especially when its freezing cold wind whilst checking out aircraft... When you get in, you appreciate the coat/jacket etc
During flight we would get naturally hot anyway.... Also watch when instructor sends you solo.... My instructor seemed to be cold and i was obviously hot.. By downwind the cabin heat had cooked me!
Not the best thing to add to the pressures
