PS. I have several sizes of dresses & pajamas; please ask!
Consider this: My Santa photo sessions are a unique experience that celebrates the wonder of Christmas through a child’s eyes. Pajamas are what children would naturally be wearing when Santa visits their homes on Christmas Eve. Pajamas for photos with Santa capture some of that magic that kids feel when they are tucked into bed the night before Christmas.
After everyone arrives at the North Pole, they will discover Santa's secret closet! This closet will be filled with his red suit, hats, and boots. Santa, of course, will be the main focal point, so you'll want to select colors that complement his red suit rather than compete with it or blend in. Santa will make a grand entrance on into the scene after they start trying things on
At this point, it's up to you whether they stay in their PJs or change into traditional Christmas attire. I recommend they remain in their PJs and simply remove their coats or bathrobes to try on Santa's coat, hat, and other accessories.
NOTE: Most of the examples above are not my photos; I will have the SAME SANTA as always. These are for you to use to choose clothing.
