It seems that all the weddings that were canceled over the past year are back on, albeit maybe a little smaller and with vaccination requirements. And what a wonderful way to get back into dressing up nicely! If you’re searching for a pretty dress to wear to an event this spring or summer, I have good news for you. Once upon a time, there were only cotton shifts available in the sustainable version.  But now, you can find cocktail dresses from a dozen sustainable and artisan designers.

And in a happy side note, I also found some pretty dresses in extended sizing, and lots of models of color! We’re getting much more diversity than when I started doing editorial roundups just a few years ago. Things are looking up in more ways than one!

Pour yourself a glass of champagne. We’re going shopping.
