I love your dress, Mojo---you will wear that dress many times I am sure. I bought a mint green one in a similar style for my son's wedding 4 years ago. The style is very flattering....and forgiving, as I like to say. I've worn it so many times.
Lots of fun options for you with the navy! 4 summers ago both of my sons got married, a month apart. They are 2 of my triplets, and I wanted a special dress for each wedding. I found dress #1 easily, but then agonized for weeks over dress #2. Never did feel that great about it, so I am happy for YOU that that big decision is behind you!
Given that you had 2 hips replaced and are now preparing to put on some heels and perhaps even dance at the wedding, you must truly feel that your cup runneth over! I've been outside in my gardens all weekend, marveling at all of the things I can do with relative ease, (and some pacing and good sense;) compared to last summer. Life is good!
