My first Sunday offering is the Maxis Santa suit converted for children and toddlers. No EPs or SPs are required.
I also included a retexture of Dedital Sheep's Santa Hat accessory for all ages to match, but the mesh is NOT included. Grab it here. As far as I know there is no accessory of the Maxis santa hat, but there is a hat hair conversion for toddlers here.

ETA: If you have Happy Holidays I've enabled the santa cap for girls.
