We may have seen record-high temperatures this week, but that didn't stop celebrities from heating up the red carpet with loud, vibrant dresses. Stars kept their makeup and accessories simple and let their notice-me outfits do their job.

Amanda Seyfried made the crowds at the Comic-Con 20th Century Fox panel green with envy in a Prabal Gurung Resort 2012 dress and black sandals. The actress cut her gorgeous hair in April -- after hinting a year earlier that she was getting bored of her long locks -- and the style is growing in nicely. As usual, Seyfried kept her makeup light, letting her radiant skin do the talking.

Emma Stone tackled not one but two punchy colors at the New York "Friends with Benefits" premiere. Wearing a Giambattista Valli Fall 2011 crimson sweater and neon pink skirt, Stone balanced out the look with nude Christian Louboutin heels and a subtle metallic clutch. The star did her classic fresh-faced look with a hint of a smoky eye, and we are loving it.

A very pregnant Jenna Fischer glowed at the Los Angeles premiere of her new movie, "A Little Help." She donned an Ana Maria gown with empire-waist and minimal jewelry, sweeping her hair into an elegant side-bun.
