So the lady that's doing Rileys birthday pictures just told us the location and it will be at a creek. She won't necessarily be in the creek except maybe her feet. I have NO idea what her outfit should be now. I already have her smash cake outfit picked out just waiting for it to be here. Should I have a outfit for pictures outside, AND of we do pictures in the water?? To me it seems like a lot of changing though. I'm so lost!
