Julia Louis-Dreyfus — an early winner for best comedy actress in "Veep" — had on a much more straightforward metallic column by Monique Lhuillier.
January Jones, who normally goes ultra sleek to contrast her retro "Mad Men" character, did a more romantic turn in a dusty-rose lace gown by Givenchy.
Sofia Vergara wore the body-hugging gown and mermaid hem that's she's known for, but anything less than this sort of bright red Vera Wang gown and oversized emerald Lorraine Schwartz jewels would disappoint the crowd.
The "Modern Family" star also had a plug for her retail partner Kmart, saying she had on underwear from there. "But you can't see that unless you rip the dress."
Tina Fey wore a royal-blue gown by Narciso Rodriguez that had a very open neckline but otherwise had the designer's minimalist touch. Allison Williams wore a similar color. Her gown by Ralph Lauren, strapless and an utterly clean silhouette, showed confidence.
Connie Britton didn't shy away from embellishment with a gold-on-teal gown by Naeem Khan. Lena Dunham stood out on the carpet, too, but her floral-print dress seemed one of the fashion misses of the night.
"Games of Thrones" star Emilia Clarke might not be a household name yet, but she wore a skilled red carpet designer: Donna Karan. Every geometric leaf cutout was cut and folded onto the actress' body. She's likely landing on fashion watchers' lists.
Heidi Klum turned up in a hard-edge halter gown by Versace, while "Top Chef" host Padma Lakshmi, another seasoned poser, turned some heads in her sleek, white KaufmanFranco with an illusion halter neckline and a just-right flash of skin at her hip.
Perhaps more important than the established style stars looking picture perfect, were the new names — and the up-and-coming designers they chose to wear. They all added a jolt of excitement that's been missing from what largely over the past few awards seasons have been a sea of perfect, classic black dresses.
Thakoon has dressed Michelle Obama, but the label still wasn't a go-to for the awards circuit. That changed here with "Orange is the New Black" star Taylor Schilling's white gown with a delicate halter top, mostly bare back and high slit.
Romona Keveza had an impressive showing with dresses for Anna Gunn of "Breaking Bad," who wore an asymmetrical black beaded top over a light pink skirt, and Carrie Underwood in a more straightforward purple strapless.
Zosia Mamet of "Girls" wore a watercolor-print dress with a white bib front with black on the bustline by Honor, a new player on the celebrity circuit. It wasn't the typical Emmys look, to say the least — and that's going to get her photo beamed around the world.
Aubrey Plaza wore a harness-top gown by Marios Schwab that featured black lace over a sand-colored gown.
Keirnan Shipka showed she can go stiletto sandal to stiletto sandal with her fashion favorite "Mad Men" co-stars. She wore a bold floral top and a retro-vibe flared print skirt with hand-embroidered overlay with chunky jewels by Delpozo. Christina Hendricks was practically tame in her more delicate black Christian Siriano, but she managed to add her own vavavoom.
