We know what you’re thinking: It’s just J.Lo in another barely-there gown. But the one-shoulder Atelier Versace design actually upheld the evening’s theme quite well, with a fiery beaded dragon and embellished flames covering the singer’s torso in some very strategic spots. Ruby-accented earrings and a spinel statement ring rounded out Lopez’s red-hot ensemble. Meanwhile, model Karolina Kurkova collaborated with celebrated sportswear designer Tommy Hilfiger on her short and sassy gold-embroidered crimson couture creation. Giuseppe Zanotti serpent-inspired stilettos snaked up her legs. And the Asian influence continued to her jewels: Kurkova’s earrings were crafted from antique Chinese mother-of-pearl gaming counters.      ON LOPEZ Ring in 18k pink and yellow gold with 5.37 cts. t.w. spinel and 0.45 ct. t.w. diamonds; $9,800; Ivy New
