I don't know if you can obtain a replacement strap through Fendi or not. I will say, though, that the men's Strap Yous are generally a few inches longer than the women's. If you can find a men's Strap You that you like, it might be long enough for you to wear crossbody.
Oh, didn’t realize there are Men Strap Yous. I wonder why my SA didn’t show me those, or maybe my local Fendi has limited straps. Thanks for the response, babe! I tried the straps from my other bags, but of course it will never be the same. [emoji21]
