So I just bought and added them to my wardrobe. However, when I went to wear my outfit on site, the shoes wouldn't show up. I realized that despite the shoes being in my wardrobe (and showing up when I tick 'only show items you own'), I still get 'search shops' instead of 'item in wardrobe!'. Therefore I can't actually wear the shoes. : (

I tried removing them and re-adding them to my wardrobe, but no dice.

There's a delay (maybe 15-20 minutes?) before newly added items will show on your HA. I don't know if it's intentional or a bug, but it's been happening for a while (I ran into it during Morostide)

Oh gosh I didn't know that! It's working now so I guess that was the issue. Thanks for letting me know.
