Girl, keep that bag and wear the heck out of her!
Oddly enough I'm hunting this same bag except with GHW on my next trip to Paris in December for my birthday. I've wanted Rouge Casaque for years and ask for it every time I go to Paris.
On my last trip in November, I got your HG Gold B35 GHW but haven't used it a single time. Working from home I just haven't had an opportunity or the right outfit to wear her. It's easier for me to grab a Neverfull or Speedy when running errands. When I reach for a Birkin it's usually my first and HG Raisin or Blue Nuit. I just find them more versatile. Regardless, the Gold was on my list of must have colors and I'm actively buying outfits to complement her so that I'll use her soon. Hopefully!
