Ultra-violet is the most vibrational color of all, and Peter Dundas tripped out on it in his spring collection for Emilio Pucci. Why not use this photo of Natasha Poly in his swirly, tie-dye gown as inspiration for some psychedelic makeup and hippie hair?

To replicate Poly’s swingy mane, spritz on Bumble and bumble’s Surf Infusion.Enhance and smooth waves with Sarah Potempa’s new Beachwaver S1, ($129 on ulta. com). Or, if you prefer to airdry instead, Bumble’s Don’t Blow It (H)Air Styler will tame free-wheeling flyaways.

Makeup-wise, Urban Decay’s eye shadow in “Tonic” and Revolution High-Color Lipgloss in “Bittersweet” are about the punchiest purples you can find. Feel the vibes.
