90’s me be jealous 🥹
Color: #04 Bronze
26 years later, here I am- the sparkling unicorn of an adult the late 90’s child version of myself DREAMED of while coating ✨EVERYTHING✨ in glitter and shimmer. Only now, I have an Amazon card and the impulse control of a toddler, so I sparkle now 🤩.
Am I 40 years old? Absolutely.
Did my kindergarteners at school ask why I sparkle now? Absolutely.
Did my mid-life crisis self lie to them, and say because I’m a magical unicorn? Absolutely.
Did they believe me? ABSOLUTELY.
10/10 recommend, but only if you too want to live your best magical unicorn life!
Technical notes- the smell is light and lovely. It dries without a “feel” so I forget I even have it on. The shimmer is noticeable, but not like I rolled in glitter. I’m enjoying the bronze glimmer color, but I’m sure will be back soon for more. I could easily spray more if I wanted to be more blatant with my attention seeking. I will absolutely be using this stuff from now until I’m in my grave with no shame!
Fantastic all around 🤌

Love the glitter!
Color: #04 Bronze
This glitter body spray is everything! It’s water based so you have to shake and mix the product first before you spray. It dries quickly after that. I mixed a little with lotion too to spread it out & it still applied well which I love. I did go through half the bottle but I used it on me & my friend. Definitely worth the purchase.
