I have this off-white denim jacket from Folk - https://www.stuartslondon.com/folk-orb-ecru-denim-jacket-f2931w-p25914 - which has pilled quite a bit on the shoulder/back because I usually carry a bag. I am wondering what the best way to remove the pilling off the jacket would be? I haven't tried anything yet because I love the jacket and don't want to experiment too blindly.
