I would try and return OR suggest they put it in their next auction and waive their sellers fees on the grounds that the odour was not disclosed in the description of the condition of the bag.So…..I purchased a bag from this sale and it is beautiful, but it has the most god awful cigarette smoke smell. Horrible. Does anyone have this experience? And any suggestions how to get it out? My bag is Fauve barenia and toile. Help!
The fact that your bag contains toile makes me think you will never get rid of the smell as it is probably impregnated into the fabric.
Worse it may make your closet smell too

I always when considering purchasing at auction request further details (like odour) even if its NOT given in the condition report available for download, And I am always wary about bidding for an item at auction that i am unable to go and view.
I say this because even reputable houses sometimes miss things and its really important to actually hold the bag and inspect in person.
Hermes bags are never inexpensive so buying remotely requires extra diligence.
