It’s nice outside so I would like to wear an open back dress.

Of course it’s great to take advantage of a beautiful day or night and an open back dress is a great way to do it. One of the first things to keep in mind when deciding to wear an open back dress because it’s a nice day is, where are you going? It may be a nice day/night outside, but open back dresses aren’t appropriate to wear to the place you are going. So, definitely keep your destination in mind.

Another think to keep in mind is the amount of activity you may be doing. Sure, you could wear an open back dress to a picnic, but what if everyone wants to play volleyball? Is your dress flexible enough for you to participate in the activities that will be going on?  
Now, if you have taken into consideration your destination and your activities, then flaunt away!!!
