Bella Hadid goes braless yet again in another sheer look for Paris Haute Couture Fashion Week: Pics

Bras are so last season! Bella Hadid hasn't felt the need to sport many undergarments while walking the Paris runways this past week.

The 20-year-old supermodel first turned heads at the Alexandre Vauthier show on Tuesday in an entirely sheer top. Then on Wednesday she was at it again for the Fendi show.

Hadid sported a sheer dress with carefully-placed blue embroidery, which covered her nipples, but not much else.

She paired the floor-length gown with lacy blue undies and royal blue heels.

Hadid was joined on the runway by pal, Kendall Jenner, who went for a more conservative ensemble, in a black mini-dress, complete with a cape and black floral embroidery.

Hadid posed backstage as Jenner snapped her photo, capturing the moment on Instagram.

"Kenny on the film at @Fendi," Hadid captioned the sexy shot.

Earlier in the day, Hadid strutted her stuff in the avant garde Maison Margiela show, sporting painted blonde locks, and a sheer dress with jeweled detailing and a gold bodysuit underneath.

Thank you so much @jgalliano @lexyroche for having me in your show...Just being able to watch you work was an honor for me."
