On the weekend, the stunner - who attended a wedding in New York - posted a picture in which she wore an in-credible designer frock by Peggy Hartanto, but some found it difficult to get their heads around the style of it!
Lucy (and her killer tan) glowed in the black satin scuba number which boasted a flippy midi skirt and a cutesy peplum but it was the waist and different neckline that garnered the most attention.
Taking to the comments section of Lucy's snap, one of her followers wrote, "Omg, not sure what to make of this dress! Is she wearing a bra?" while another said, "No! The bottom's lovely but the top..."
In fact, a few followers thought Lucy was completely naked from the waist up save for the fancy plunging chest detail, but you can all breathe a sigh of relief, because if you look closely, the frock actually boasts a flesh-coloured insert (it's there, trust us!) blurred by the camera.
No wardrobe malfunction to see here, people, phew!
Even though gorgeous Ms. Meck's dress was pretty unusual for a wedding, the rest of her fans thought she looked AH-MAZING as usual.
One said, "That dress is everything! Beautiful!" while another wrote, "Spectacular! You look sensational!"
We couldn't agree more. Here's hoping she didn't upstage the bride. Eek!
