I normally don´t like black bags very much but my first birkin was a black box birkin with GHW and I did not regret my decision for a moment.
I fell inlove with this leather the first time I searched on this forum. it is one of the most beautiful leathrs I ever came buy (exept barenia maybe...).
if you are going to buy from a reseller, please think about black box. this is a bag you can hand on to your daughter. it looks stunning now and will in 40 years!
I hope this helps a little bit!!
My first was Gold w/PHW. A month later I was offered a Black w/GHW. I am a neutral, classic gal and these two are perfect for my wardrobe. I have never regretted going for Black (or Gold) over a pop of color, no matter how boring some may think it is. It is timeless and classic and a gorgeous no brainier bag that goes with just about everything. Best money spent. :)
