Gabrielle Union's latest look has fans praising her distinguished sense of style.

On Tuesday, the 49-year-old actress took to Instagram with a carousel of photos, posing in a black, open-back, long-sleeve Alexandre Vauthier dress with a pair of matching stiletto boots. She paired the rhinestone-embellished ensemble with a simple and soft makeup look, along with a slicked-back, braided up-do.

"Time to shine, ma lady," she captioned the post for her more than 20 million followers, alongside a sparkle and disco ball emoji.

The actress also tagged the upcoming film, "The Inspection," about a young gay man who's been rejected by his family but, ultimately, finds the support he needs by joining the Marines. Set to be released on Nov. 18, Union stars alongside Jeremy Pope and Raúl Castillo.

Fans were quick to comment on Union's "regal" appearance, with many praising her "ageless" complexion.

"First of all, how is it humanly possible for you to still look no older than 30? Secondly, you look so stunning and sophisticated in these. True royalty!" one Instagram user commented.

Another wrote: "Regal and stunning!"

"Love that dress! It reminds me of golden era Hollywood glam," someone else chimed in.

"I love that outfit!" added another.

One fan penned, "You look so freaking good, I can't get over it. An ageless queen! And that dress is so perfect on you."

"The dress is fabulous!" a fan wrote.

Another person added, "This outfit is so gorgeous and clean! But it's the skin for me!"

Last month, fans applauded Union's ageless appearance after sharing two carousels of summery photos, wearing a fluorescent yellow $330 maxi dress by designer Kwame Adusei.

"Alien Guest Star. Hoping to be bumped up to series regular," the "Bring It On" star captioned her first post, while adding, "BTS from the spaceship," to the second.

"Ma'am, you are literally aging backward and no one can tell me otherwise. You look amazing! This dress looks beautiful on you. I needed some fresh summer-style inspo and this is it!" one Instagram user commented, while another weighed in with: "When are you gonna age?"

"Just tell everyone else to go home. Lol," wrote "Half & Half" alum Essence Atkins.

"Oh, you just gone keep blessing our timeline I see," one fan added, while another chimed in saying, "She is stunning. You can’t beat that natural beauty. Go 'head, girl."
