Recently I’ve seen the “You Da One” singer in some very questionable and down-right revealing outfits, but you’d never know it from what the 24-year-old wore today.

Rihanna joined Brooklyn Decker for the UK press conference and photocall for their movie “Battleship” at the Corinthia Hotel London in a striking Alexander Wang dress!

She selected the green mustard halterneck dress with stunning gathered detail starting from the back of the waist to the knee-length hem. This design comes from the Pre-Fall 2012 collection.

Riri finished off the look with a classic pair of black suede “Pigalle” pumps by Christian Louboutin and lots of diamond encrusted gold jewelry. I think her bangs are really heavy, and borderline make her hair appear a bit helmet-ish, but all-in-all it was a good look. An improvement, indeed.
