I mean it's just so iconic!
The one I have is by collection and I love it so much (I need to wear it more!) I like like wearing black mascara on my top lashes and blue on the bottom I just think it looks so cool. I think it's the perfect makeup product to add to your collection I usually use it when I'm doing fun glittery eye makeup but it also looks really cool as just a little pop of colour. I love coloured mascaras I also have green and purple but the blue is so much brighter and will always be my favourite.
