The "July" singer wasn't afraid to free the nipple during an afternoon outing in the City of Light, as she stepped out in a black chest-baring gown on Jan. 24.

Noah's Stéphane Rolland Haute Couture design featured a large chain-link attachment that barely covered her breasts and an even more plunging neckline that swooped just above her belly button.

The 23-year-old's head-turning dress, which looked like something out of Morticia Addams' glamorously macabre closet, also included long sleeves and a floor-length train for a mini dose of modesty.

She paired her outfit with sheer pantyhose, black strappy heels and bleached eyebrows.

For the Marine Serre show on Jan. 21, she rocked a bold catsuit with the brand's famous half-moon pattern and layered a baroque-printed bodysuit on top.

During Alexandre Vauthier's Jan. 24 presentation, Noah donned a sparkly bikini that she wore underneath a completely see-through pleated gown.
