This dress fits true to size. I'm wearing size small here (4/6) and I'm 5'8" for reference.

For a simple fall look, I'd add a scarf and boots. I love how this color looks with leopard print!

You could also do an over-the-knee boot with a warmer scarf. Plaid always feels right.

Finally if you wanted to wear this dress on cool-but-not-quite-cold days, add a denim jacket and some ankle boots.

Grab one (or two) of these

, you won't be disappointed! My orange rust color is sold out at the moment, but there are 7 other colors to choose from (and the orange might get restocked). I'll link them all in the widget.
