I've tried removing items from my avatar, but it still won't let me click or or preview it. I don't know if this is just me or if it's wider. I hope this helps?

I just purchased it to try and it seems to be working fine for me. Hopefully it's sorted out for you soon.

is it in the leftmost column of your wardrobe? try adjusting the size or zoom of your browser window; at a certain scale, the part of the page containing the avatar preview overlaps that section of wardrobe items, rendering them unclickable. it has nothing to do with the items themselves, just a functionality bug/oversight.

Here is a suggestion that a good friend of mine told me. Try running your cursor along the very edge of your item and the cursor shape should change so you can select it. Probably have to mess a bit with it and carefully go to the very edge. Took a bit for me but I got it.
