Ah, The Grammys. One of the highlights of the awards season. The extravagant dresses, the mind-blowing performances, the chic after-parties.  And let's not forget that this occurred during the same week as Valentine's Day as we saw swoon-worthy moments between Queen Bey and Jay and the always adorable Chrissy Teigen and John Legend. 

The couple that really stole the show, though? Rihanna and her blinged out flask. In a sea of Cartier and Harry Winston jewels, the most enviable accessory at the Grammys was Rihanna's diamond encrusted drinking accessory. Leave it to her to make the biggest splash at an awards ceremony where she didn't even win an award or perform (WTF, Grammys?) and to originate the hottest new fashion accessory of fashion month even though she wasn't even on the same coast as NYFW. Check out some stylish flasks perfect for a night out!
