I was looking in my Starbazaar sales and I saw this:

(I blocked out her name because I believe she is innocent)
So I asked her if she would sell me it back immediatly, but she said she has seen it in my Suite before, so I looked and did not find the shirt! But, when she explained where it was to me properly, I found it in a Starbazaar bag in my suite. I was like 'I didn't buy that!'
And it's still a mystery now....
