Felicity Shagwell may have been on to something: With fans such as Julia Roberts, Salma Hayek, and Madonna — not to mention the psychedelic housewife ensemble Amber Valetta models in Versace’s latest ad campaign — Pucci prints are the pattern du jour. The distinctive, bright geometric designs, first worn by Capri jet-setters in the 1950s, have also trickled down to the masses, with labels like dollhouse, Rampage, and Coolwear offering their versions. ”Pucci still looks new and modern,” says Tiffany Dubin, coauthor of the just-out Vintage Style. ”People are craving color and a sense of fun as a reaction to the early-’90s uniform movement. [Now] it’s very much a party moment.” The festivities extend to the original Italian design house, which is flourishing under the new ownership of luxuries giant LVMH: Pucci just christened a store in Milan this month, with a Palm Beach boutique set to open in December.
