Do I need to dry-clean my dresses after just one wearing?

[egbok]

Hi,

Just started a new job and bought some smart shift dresses to wear - some dry-clean only, some hand wash or low-temp wash. This may be a silly question, but do I need to dry clean or wash after one wearing, or is there some way to freshen them up between wearings?

I'd be tempted to hang it on the line, let the lovely ozone get to it.
Btw, I regularly wash dry-clean stuff

Lakeland plastic do some sort of tumble drier thingy to clean/freshen stuff up. I had good results on jumpers that I didn't fancy washing and was too mean to dry clean.
