This outfit, as many of Slastena's styles are, is very classic, flattering, stylish and polished. I love anything gray and am realllllly into statement necklaces right now (as seen here, here and oh, here and here). I love the necklace (from Banana Republic) she's wearing!
I love how Slastena from About All and Nothing At All shows the outfit pieced together and then IRL:
And best yet. Here outfit deets are available via Polyvor with links directly to the pieces.
