It’s pretty clear that the easiest way to update your outfit right now is with the simple addition of a jacket. I know it's not ground breaking fashion news, however one of the things I love about this trend is that the styles are so diverse and it seems there are no strict rules. Styles include the tuxedo, military, denim, sequined or leather, whatever your choice of jacket, it’s the unavoidable essential accessory this season (yes I know we're coming into Summer but I’m pretty sure they’ll be just as important next Winter).. You can do them with the traditional items like leggings and jeans, I’m loving them with a floaty dress or even a pair of shorts (Olivia Palermo & Blake Lively Style) Here’s some inspiration for the week ahead...Rachel Bilson & her cute Cropped JacketBlack Lively - One the set of Gossip GirlVanessa Jackman BlogOlivia Palermo - The Jacket with Shorts & Ankle Boots - I like, could I pull this off myself?
