Not sure if this is the right place for this, as I guess it's technically a housekeeping issue, but here goes:
I wore a full length, ivory, beaded silk dress to a 'do' a week or so ago and fortunately managed not to spill anything down it
I will be wearing it again in a couple of weeks and am unsure whether or not to get it dry cleaned in the meantime.
It is mostly clean, but does have some mucky marks around the hem from going for a cigarette walking around outside. Also one small black mark where some nobber stood on the hem while we were milling around 
The thing is, I am pretty sure if I did clean it before wearing again it would have achieved a similar level of dirt very quickly so I don't think anyone would really notice that it was a bit dirty.
I'm reluctant to dry clean it because the beading is very delicate and I don't want to damage/discolour it.
WWYD?
