I was looking into the stingray boy as well but I believe it's only available in the small boy, which is pretty tiny. I feel like it won't fit much more than a woc? I don't have any boys so if anyone could give me some input on the size of the small boy, is greatly appreciate it [emoji4].
I believe I've seen some in the Old Medium size as well, I think they're just a lot less common than the small/mini ones. I know the small boy is less than 10 inches across, but I imagine the WOC fitting a bit less just because it's very flat. I like the fact that it's just that much bigger though regardless, just makes the bag totally pop! Either way, they're both stunning and worth it IMO
