I used a 5mm hook and 2 strands of 8ply acrylic yarn for the doll, the hat and the pizza.

I added a round of slip stitches to the outer brim of the hat.

Glasses
I made a wire frame for the glasses.
I wrapped the lower parts of the frames with 1 strand of white yarn, then worked a row of sc across the top of the glasses - including both side arms with a 2.5mm hook and 1 strand of white yarn.

Pizza
I made a pizza top, stitched the pepperoni in place, then made another circle in all beige for the underside of the pizza. I then joined the top and bottom of the pizza together with a round of reverse sc.

For the pepperoni on the pizza, I made 4sc or 6sc circles with a 2.5mm hook and 1 strand of red yarn.
