(InStyle) -- Oscar night is Hollywood's main fashion event, and most notable on the red carpet this year was our favorite actresses stepping out in uber feminine -- not just fashion forward -- looks. 

Indeed, from the most delicate shades of blush to the boldest fuchsia, the red carpet turned pink! Exaggerated ruffles, soft draping, frothy fabrics, dramatic trains and Cinderella-esque silhouettes gave new meaning to the term Hollywood royalty. 

The few celebrities who bucked the romantic trend, including Sarah Jessica Parker, Sandra Bullock and Meryl Streep, chose sophisticated styles with retro vibes. 

From a timeless beauty (Demi Moore) to a graceful Hollywood icon (Meryl Streep), here are the night's fashion winners. 

Demi Moore 

Demi Moore often chooses classic, tailored cuts, but last night she glowed in a stunning blush-toned Atelier Versace silk organza gown with petal-like tiers of ruffles. She finished off this softer look with Van Cleef & Arpels tassel earrings and diamond cuffs, a gold leather Salvatore Ferragamo clutch and dress-matching Versace satin sandals. 

Diane Kruger 

The ever-flawless Diane Kruger turned to her favorite designer Karl Lagerfeld for her cream and black chiffon gown from Chanel Haute Couture. Both edgy and feminine, the design featured a pleated and ruffled skirt that led into a bow-bedecked mermaid train.

Jennifer Lopez 

We love the way Jennifer Lopez commands the red carpet in dramatic dresses, and her choice this year was no exception. Yet rather than going sexy (down-to-there Versace, anyone?), the diva went spectacular in a full-on princess-shaped icy pink Armani Prive confection with a Swarovski crystal-studded waterfall train.
