With nail salons back open for business, my Saved folder on Instagram is rapidly filling up with manicure inspiration for the season ahead, and I've noticed one unexpected look that's trending right now: glitter nails. Yes, while pastel hues and cute nail art still look set to be classic summer staples, the coolest girls are dressing up their nails with sparkly polishes and pops of shimmer. And I'm not mad about it. After all, while glitter nails have traditionally been popular during the winter months, the fact that party season was nonexistent last year means that glitter is coming out to play this summer instead.
