I'm so sad to see this problem is becoming more like an epidemic. I have received countless PMs and emails from friends here on the forum. SOs have been showing up smelling like stink bombs on many occasions. Not everyone is willing to go public with this problem. Sad that you happen to also have a stink bomb!
One thing I discovered is that if I am in my SUV, with the stinky bag on the seat next to me and the sun is shining on it... it will stink. The smell is VERY obvious on hot days with tons of sun but the bag also smells in the cold weather when it's in the sunlight for about 30 minutes. I discovered this 2 weeks ago after getting my bag back from the boutique... claiming "Paris didn't smell a thing". Yea right. My bag never left that boutique, let alone went to Paris and back in less than 3 weeks! They couldn't smell the bag in the indoor, open aired boutique so I was accused of "reading about this problem on the Purse Forum" but that the problem doesn't exist in "Epsom bags...Paris is only aware of it in Togo".... Meanwhile, the bag stunk up my SUV during the long and infuriating ride home... Imagine being told that after carrying around a dead skunk Birkin for months bc you're too scared to cause any drama or have confrontation in the boutique?! I'm the biggest fool ever. Send your bag back immediately. The smell never goes away. Don't hold onto hope like I did... it will just make the boutique reluctant to help you.
