Helen Mirren of 'Prime Suspect' Looks Elegant in Yellow Fitted Gown with a Train

Helen Mirren proves that she is an ageless beauty in an elegant yellow dress that flaunts her flawless body!

Yesterday, actress Helen Mirren was serving major goals at the premiere of “The Good Liar" in New York.

The actress was no doubt feeling herself as she shared a snapshot of her gorgeous dress on Instagram.

As seen in the photo, the 74-year-old looked stunning in a fitting yellow dress with long sleeves and a plunging neckline.

The elegant ensemble had a flowing train and a waistband that accentuated her lithe waist. Mirren kept things natural as she boldly rocked her grey hair and bright red lipstick to compliment her milky skin.

Staying true to her playful self, Mirren was seen posing against a background with vehicles.

She wrote in the accompanying caption:

"Screening premiere of The Good Liar in New York. Later that night after the RedCarpet, I got together with some traffic control! A great stylist ( lee harris) sees all possibilities."

As seen in a post shared by Fashion Bomb Daily on Instagram, Helen's dress was a custom Brandon Maxwell dress which she paired with a Tyler Ellis clutch.

The "Excalibur" star is known for serving major fashion goals for any red carpet event she attends. Just last week she stunned in a regal teal blue gown at the premiere of "Catherine the Great" in Los Angeles.

The figure-hugging dress featured dramatic bell sleeves and a regal cape that suited the actress character in the HBO miniseries.

Daily Mail reports that she also brought her a-game for the UK premiere of the series dressed in a black peplum house and wide-legged pants.

Going all out for her look, Mirren kept in theme with her character as she arrived on the red carpet carried in a litter vehicle accompanied by two guards.

While speaking about her intense sex scenes in the four-part series, Catherine revealed that she enjoyed shooting it in front of the entire film crew.

According to News.com.au, the series, which was released in October, focuses on the life of the Russian empress.

Helen's good looks have kept her in the news from time to time, and this was the case recently when she was compared to Keanu Reeves' new girlfriend, Alexandra Grant.

Newshub reports that despite the 28-year-age gap between Alexandra and Helen, fans couldn't help but mistake them both.

Addressing the speculations at the premiere of "The Good Liar," Mirren said:

“That was very flattering on me, you know because she's lovely."

She also revealed that she is good friends with the "John Wick" star and congratulated him on finding Grant.
