Lasted all night long!
Pattern Name: classic
These were perfectly what I envisioned for the Coldplay concert! I’m a girlie who likes to glam up and these did not disappoint. I was hesitant to see if they would stick or fall off since I would be laying them on top of a full face of make up, but nope not a single problem not even with a little sweat from all the walking and dancing. Plus I love the fact that I had a variety to choose from and they are so much fun. Can’t wait for the upcoming rave to wear again.

Completes my festival looks and doesn’t fall off
Pattern Name: classic
Definitely stayed stuck on my face even after I partied a little too hard (ifkwim), and I sweat a lot too! If it does peel off at the edges a little, eyelash glue is a best solution!
