Summer may be almost over, but we're taking a wistful look back at some particularly stylish vacations. Here, Sunday Riley talks about her recent trip to Arizona.

"I took a long weekend break from the frenzy of creating a new exciting launch (coming this fall) and headed to Miraval outside of Tucson, Arizona with my good friend and publicist, Celia Cohen."

"Being so careful with my skin (and being somewhat neurotic with sun exposure), I spent half of the trip layering Cashmere SPF 30+ to protect myself in the Arizona desert. I looked like Lawrence of Arabia on 6 a.m. hikes through the mountains with my huge Stella McCartney scarf wrapped around me to shield me from the sun!"

"The highlights of the trip included the beautiful scenery of the plants, animals, and gorgeous backdrop of mountain, amazing company, and a much-needed break from my normal routine. I also loved daily yoga and fairly intense Thai massages!"

"After four days of serenity it was back to formulating new products... soon to come! Maybe there was some more inspiration from the desert."
