How to put it together
- 1
Put on the pastel pink crewneck t-shirt as your base layer.
- 2
Layer the white and blue windowpane button-down shirt over the pink t-shirt, leaving the top few buttons open to show the pink layer.
- 3
Put on the light wash skinny jeans and thread the light pink belt through the loops, fastening it securely.
- 4
Put on the black curtain-bang wig, using a wig cap to secure your natural hair, and brush the bangs so they frame your face.
- 5
Clasp the silver chain necklace around your neck so it rests over the pink collar.
- 6
Lace up your clean white sneakers to finish the outfit.
Makeup & hair
Keep makeup clean and fresh with a light foundation or BB cream, subtle pink lip tint, and neatly groomed eyebrows. Style the black wig with a bit of hair wax to define the textured, middle-parted curtain bangs.
