Her body is a Winter Wonderland!!
The pop star wore a slinky white number by the famed Italian designer while sipping on some wine in Napa Valley with her besties.
The dress featured appliqued details and side ties that showed off RiRi's creamy, flawless skin!
To offset some of the frock's innocence, the singer painted her lips a deep burgundy, and came off looking like a total femme fatale.
