Why are my jeans always loose when I wear them? I am a size 4 in jeans. I have a 24 inch waist if you want to know.
My wife has the same problem. She found switching to "curvy" style jeans works better (as they have a smaller waist than hip).
Most jeans that are regular fit, my wife has a gap at her waist that I can stick my arm in (not small).
