<p>I put at least one shirt that goes with a suit - and the ties - inside the suit, with the ties draped over the hangar - and then put them all in a dry cleaner bag and then inside whatever bag I’m using. If at all possible, I use my own hangar because then I just take them out and hang them and can put them, as others have noted, near the shower to steam if necessary. It doesn’t matter if I use a carry or a roll-on bag as long as I don’t actually crease the suit but instead fold it gently.</p>
