Shared wardrobe platform

Last year I had 7 weddings and realised I was about to buy 7 dresses I’d probably wear once. Instead, my friends and I started sharing outfits between us. We put everything into a shared folder, and before buying anything new we’d check there first. It actually worked way better than I expected.
It got me thinking… could this be an app? I’ve been playing around with building a really simple tool where you create a private group, upload what you own, and request to borrow from each other. It’s very early and I’m mostly just testing the concept.

Is this something people would genuinely use? Or do you think you already do this anyway and there isn't a need for another app?

Curious how others think beyond my friend group.
