The Big Trade Off is hosting The Big Makeover - challenge where the participants are provided with premade sim(s) and they'll have to make them over INCLUDING some new custom content specially made for that Sim. It only started but there are already few Sims posted thus far so I'll just toss images and mention what new content they have included :3
Hair Recolor, Shirt Texture Edit, and New Meshed Bottoms
Hair retexture, clothing recolour
Hair (shaved "retexture" of base game bald hair)
Hair and glasses. Hair is a simple edit of Pooklet's volatile on Lasky's original hair. The glasses are an actual set and there are 9 recolours. Both meshes by Nouk and Tamo are included.
I made a recolor of the Chagasi beard and made a brand-new facial cut for over the sim's left eye
Pale skin color, dark brown eyes, and grey tiered dress
So already tons of great stuff, we'll try our best to keep you updated whenever there's an update
