Kim Kardashian was spotted arriving at Miami Beach's Eden Roc hotel wearing a flowing red sheer gown without a bra.

The Keeping Up With the Kardashians star was returning to her hotel after a quick trip to Mexico City, where she attended the 40th Anniversary party for Cosmopolitan magazine.

She tweeted a photo of herself in a white dress (below), with the caption, "Ready for my night out with Cosmopolitan Mag 40th Anniversary in Mexico City."

She also tweeted another image with the message:

Last nights look! YSL dress, Tom Ford heels. Make up @realmakeupbymario Hair @clydehairgod instagr.am/p/QZWo_DuS1p/
