Y2K Diamond Collaboration is a huge makeup collection packed with colorful cosmetics for creating glossy, playful, early-2000s looks. The Sims 4 Y2K makeup cc collection comes with eyeshadow, eyeliner, blush, lipstick, lenses, and nose shadow, so you can build an entire Y2K makeup look using pieces from one download. You get an impressive number of shades to experiment with: 70 eyeshadow colors, 10 eyeliner colors, 35 blush colors, 50 lipstick colors, 40 lens colors, and 20 nose shadow colors. With so many swatches, you can mix and match the makeup for soft Y2K glam, colorful cyber looks, or more dramatic party-inspired styles. The collection works for all genders and supports makeup sliders for even more customization. The set is compatible with the base game.
