Dressing for dinner when it's hotter than blazes

No, really.  I did just title this post what you saw.  It's hot.  Mind you, I'm not complaining as much as I'm simply trying to figure out what to wear to a casual dinner out (in public) and still look put together.  I don't typically wear tank tops, even at home.  I don't wear a ton of shorts away from home, so when it's over 85 degrees, and then even over 90, a woman needs options!  Here is one look I put together which I know will be on repeat for the summer.

This sleeveless duster is game changer for my wardrobe this summer.  I've linked some similar below along with other possible pieces to this look.

When you want more than simple t-shirt and shorts the duster is a great addition.  I love it also paired with a fun screen print t-shirt to a different look.  For shoes?  More casual, add flip flops.  More dressy?  Add a great wedge or espadrille.  Another option would also be a great sneaker or platform sneaker.  Imagine a cooler evening.  How about a simple long sleeve t-shirt, cropped distressed jeans, wedges, and the duster?  

Tell me your favorite HOT weather outfit!  I'd love to hear what you're putting together.
