Dear _________,
I love that we think so much alike, and have the same great taste in fashion! Thank you so much for spending the day with me to help me shop and find the perfect dress to wear to the rehearsal dinner. After going to a half dozen stores with no luck, you didn’t let me give up. And at the last little boutique it was you who ran across the perfect dress on a rack I hadn’t even noticed! Thank you for sharing my shopping adventure.
