Nothing like a multi-use dress, no? Wearing this maxi (seen here) as a duster today.
UPDATE (How to tie this dress): I tied a knot in front as tight as it could go (preference), then tied a second knot. Took both ties neatly to the back to make another tie so it shapes my body the way I want and you can also see my tank/jeans properly. You can obviously get creative with it too.
