I would have NEVER considered this 6 months ago if someone had suggested it....
but another SA and I were recently discussing this..and while the company absolutely DOES NOT recommend it...it is a personal risk/preference. I do know a loyal customer of mine who has put several of her light colored bags (white optic sig. Carly for example) in the washer...and it looks like it was bought yesterday...
Needless to say, I clicked on this link because THIS VERY DAY I put 2 of my own Coach bags in the washer after struggling to spot treat them. They were both Hamptons Weekends hobos (from more than a year ago)...I wear them only in summer and they are my least expensive bags (one in black and one in sky blue). I washed them on the delicate setting using Woolite...and they came out GORGEOUS...all spots on either bag are GONE. BUT...I highly recommend exhausting all other recommended cleaning methods before resorting to your washer.
I will not be putting any of my other bags in the washer...just these in the future.
