We travel carry on luggage only and use the laundry but not for dockers or nice shirts (those can be wash and press). Use the laundry bag for pjs, socks, tees, shirts, underclothes - things that can be worn without a lot of care. Travel in hiking fabric pants so those can be washed in the shower and will dry overnight. Be sure to have your laundry together early and alert your cabin attendant so it goes in early.
