Katy Perry rocked a slime green dress to match her slime green hair while visiting the Mütter Museum in Philadelphia on Wednesday, but it looks like the frock's sheer fabric may have showed a little more than Katy anticipated…
Because as the singer exited her ride before entering the museum, the solid under layer of her dress appeared to ride up and give everyone a gratuitous view of her white panties!
Then again, maybe it was all part of the show. We're perfectly used to seeing Miz Perry in much more scandalous ensems than this!
Hope you enjoyed the museum's rare collection of oddities, gurl!
