Perfect Champagne Shimmer for Festivals & Events
Color: Champagne Gold - 01
Color- Champagne Gold shade. So cute! Get it! I always end up getting compliments when I wear this to festivals/concerts/event. It works great not just on your face but all over your body like arms, chest, shoulders, anywhere you want a little extra glow. It adds a really cute shimmer without being too extreme or over-the-top. I especially like wearing it to festivals or events where there are lots of lights or sunshine, because that’s when it really catches the light and looks the best. Once it dries, it has more of a matte finish with a soft shimmer rather than looking overly dewy or greasy. The champagne color blends really nicely with my neutral/tan skin tone, so it looks natural while still adding that fun sparkle. It’s a great little addition to any festival or event outfit. A little bit goes a long way. I’ve probably used this around 20 times already and still have at least half the bottle left. Another huge plus is that it washes off easily and doesn’t flake everywhere or leave glitter all over the floors and counters like some other body glitters I’ve tried. Overall, a great product if you want a subtle but noticeable shimmer! ✨

A little goes a long way, one drop is packed with glitter. Also it actually dries to matte finish, not dewy.
