Here are the onsies I made for Fisher to wear to my brother's wedding. The wedding colors were blue and lavender. I made one long sleeve and one short sleeve so we'd be prepared for any weather, or have a backup if Fisher pooped through one right away. This turned out to be so much better than buying a real formal outfit. The layers of a dress shirt, tie, vest, and/or jacket are so hot and bulky on a 3 month old. I used satin scraps for the ties, and made the vest out of a hubby shirt that was destined for goodwill. Good reminder: Do not attach your tie all the way down. Let it hang loose at the bottom so it does not get tucked into baby's pants.
