I think it depends on how much you'll need to carry. The Neverfull looks like it has a bigger capacity than the GST; however, I agree with DesignerGirl that it is so overexposed. I feel like 70% of women in NYC have the Neverfull, lol. You can't walk in the city without being bombarded by them. The GST is definitely rarer.
I have the GST and love it, but while it is a big bag, I am sometimes limited by what fits in it. That's why I am now using a Furla tote for work (huge bag). I posted about it in the Furla thread. But if you don't need your kitchen sink with you everyday I do love the GST. It does soften with use so it's not as rigid as people think.
Only 70%? lol..
Chanel is pretty popular here too though. Less so, but I still see it all the time.
I use to hate LV monogram bags. Hate, hate hate.
Then I caved and got a Neverfull GM in DE.
It's become my favorite bag. I used when I was in Florida every day - beach, shopping, everything.
If you need to lug around a bunch of stuff, you want the most lightweight bag you can get. I also love that's it's so low maintenance. Just wipe down and it's good as new.
There's a reason why so many women continue to purchase it year after year, it's just that great of a bag.
I only wish it came in a different version, like maybe a solid print coated canvas in different colors; something that doesn't scream LV from a block away.
My other bags are all Balenciaga's, a black leather Tiffany tote, and a BV. So as you can see, I'm not at all into flashy bags. But I still gotta go with the LV NF (coated canvas) being the best all around tote out there.
