Have to send a jacket tomo it has a slightly musty smell whats the best way to get the smell out in 12 hours ish?

Its jacket so i don't want to wash it. I think i've only ever worn it once so its not dirty in any way. Its been in the cupboard for a year so has a slightly mustly smell. Whats the best way to get rid of this. Its a 100% cotton. Any tips?

I was thinking 10 minutes in the tumble dryer?

Thanks for your tips! And i would have washed it before if it wasn't a jacket. It is clean. Just has been hanging up for a while.

I don't really smell my clean clothes. It was only had a tiny hint of must. Not full charity shop clothes wiff. But now it smell lovely! Just off to give it a quick iron before sending, ta for tips!
