I noticed that the Pink and the Yellow Undead Lace Edge Shirt appears differently on my avatar than the other colors of the same shirt. It also previews correcty - showing breasts - but when I put it on my avatar, it becomes a flat-chested version.

I took some screenshots of what I'm seeing:

That's a long-running issue with the beta wardrobe -- it will randomly show some chest items with the wrong base regardless of which one you're using. If you save with the clothes on it'll show properly outside the wardrobe.
