StyleList asked some serious heavy hitters their must-haves for staying in top form.
Catherine Malandrino, designer
"Vita Coco water -- I'm up to four cups a day!"
Rachel Roy, designer
"BluePrintCleanses -- otherwise, with the extremely long work hours, we tend to grab junk to fuel us; the premade juices are healthy, clean, and help in achieving clarity."
Rebecca Taylor, designer
"Music, candy, and champagne." Vices? "Milkshakes from Schnipper's, for sure!"
John Varvatos, designer
"[My] iPhone -- it's everything I need. I can check e-mails, snap a quick photo, and most importantly, listen to my music. On my iPhone, I like to listen to newer bands, as opposed to the classic rock-and-roll songs I have on my iPod. When I'm traveling for Fashion Week, the plane provides a quiet escape of uninterrupted time to catch up on the latest music."
Gucci Westman, Revlon global artistic director
"Going for a run in the morning and drinking my Pure Synergy green drink, no matter what the call time is. La Mer cloth facial masks every day." Vices? "Chocolate Mint Chip smoothie from Organic Avenue once a day -- so decadent! Greens peanut butter and chocolate bars."
Ted Gibson, celebrity hairstylist
"TW Steel watch to keep me on time. Tic Tacs to keep my breath fresh. Extra Strength Tylenol to help me with my headache from going from one show to another. A good driver to make sure to get from place to place. Starbucks venti green iced tea with one Splenda to keep me caffeinated. My hair kit containing Ted Gibson clip-on extensions, L'Oréal Professional Infinium #3 hair spray, and Tame It Shine Lotion to add shine and texture to models' hair. Blackberry Bold so that I know what show is next from Lincoln Center to Milk Studios!"
Peter Som, designer
"Pre- and post-fashion week facials and massages and always having a Diptyque candle lit. Lighting is everything when you're dead tired." Vice: "Tate's Chocolate Chip cookies or, when things get really stressful, Nutter Butters. What gets me through the craziness -- watching 'Golden Girls' reruns before bed."
Donna Karan, designer
"Yoga, kabbalah, any source higher than myself"
