Ah ok....I hardly take my clothes to the cleaners and its usually just dress pants and dress pants but that isn't often
Yeah. Some dress pants have to go to the cleaners -- if the tag says "dry clean only". Typically they'll be your nicer pants. Wool...that sort of thing.
A lot of other pants, mostly the blends (polyester, I think) can be machine washed at home and if you hang them right after, will probably not wrinkle up.
Sometimes if I'm in a bind and just need something ironed but don't feel like doing it, I'll take it to the cleaners and ask them to have it pressed. Doesn't take too long, usually.
But I think someone above mentioned this already...if you get dry cleaning, they will be pressed.
Only other thing worth noting is that sometimes people take clothes in to their cleaner and just ask for dry cleaning, when in reality they would be fine with regular laundering. Laundering a dress shirt costs something like $2 a shirt. Dry cleaning that shirt could be 3 or 4 times that.
