Welcome to the game.
To change your doll's appearance, go to the "Makeover" tab located near the top of the page.
Here, you can change your doll's:
- skintone
- hairstyle
- lip colour
- eye colour
- nose shape
- eyebrow shape
- eye shadow
- blush
- eye lashes
- nail colour

Select the options you want out of all these categories and then select "Buy". You will need to make sure you have enough money to afford your doll's makeover - to get more money, you can work every day by pressing the ($$$) button under your doll's avatar.

I hope that helps and that you enjoy the game!
