Boys -  colorful inexpensive bottoms (they will be cut) & a white tank.
Girls -  solid colorful shirt and leggings (timeless patterns or solids are fine)

I posted some examples inexpensive joggers, don’t be afraid to get a size up in girls to get the color you want.  I also posted an example of some inexpensive colorful canvas shoes if you don’t already have them.  Thanks for coming out today.  Your kiddos did great. They are going to be adorable!!! 

*I added some Pinterest pics so you can all get an idea of where I’m going with the boys costumes.
