getting my suit drycleaned today and have to transport it down south for a funeral. But have no real means of keeping it crease free or anything (it's going to be in a rucksack, ffs).
Are there any handy ways of de-creasing it when I get where I'm going? Is it true about hanging in a bathroom while you shower (the steam causing the creases to drop out or something?) or will I just look slovenly regardless?
Pack the trousers separately from the jacket.
Fold them flat, and roll them up, starting at the top (the creases are less likely to show and more likely to drop out).
Lay the jacket out on a flat surface and button it. Turn it onto its front. Fold the arms so they lie as flat as possible onto the back of the jacket, pointing to the bottom. If it's a very shoulder-padded jacket, fold the sides in, otherwise just pull them across so the width of the whole thing is narrow enough to get into your rucsac. Then roll/fold the jacket, starting at the neck, back towards you. I've heard it suggested that rolling a towel into it is a good idea - perhaps even a slightly damp one.
Pack them last, and unpack them immediately and hang them up on arrival. Assuming you have a shirt you want to take as well, do a similar thing with that - if you can remember how it was folded when you bought it from the shop (arms back, sides folded over), do that, then roll the shirt up - I generally do this from the bottom, since the more-creased bottom part of the shirt is the bit that isn't visible under the jacket.
I've never managed to arrive with a totally crease-free suit, but nothing so bad it aroused comment. Also worth getting changed into it as soon as practicable after you arrive, as your body heat will help creases drop out.
