She's got glitter in her eyes!
That is what they will say about you if you are brave enough to wear glitter as part of your make-up. Designers from Giambattista Valli and Jenny Packham to Burberry and Faust Puglisi have chosen to accentuate the eyes in this manner for their 2-16/17 shows.
I think it looks very 'fantasy-like,' and quite playful too. I for one would choose to wear glitter on my eyes at a special occasion but surely it could work with a casual look too.
