I don't think that's her panties; I think that is an attached under-layer and part of the dress.

Whitney your fashion commentary sucks. At least TRY and be clever.

I think I see some camel toe.

Wow… And with blue hair and a red purse huh? Huh!

She wanted to show that fame is ethereal by dressing like a jellyfish. She's the Portuguese man-of-war of pop.

Overall I like it, but not for a business meeting.  That cinch string at the bottom of the sheer dress is awful. The shorts would have been better if they were not modeled after the 1970's rollerskating pattern. Perhaps a leotard would have been better?

Just looks like something's missing. Minty mess.

No one is calling Katie Perry a slut. But that outfit is a hot mess.

It looks like a ready-to-wear version of something Gaga has.

Oh just get lost. There's nothing wrong with that outfit. This is dangerously close to outright slut shaming.

That outfit goes well with all those business suits surrounding it…
