And make sure to click here for all the afterparty Oscars looks you didn’t see!

The singer went from a mega Marchesa moment to a mega skin-baring moment. She narrowly avoided a wardrobe malfunction at the Vanity Fair Oscar Party in a one-shoulder sheer-paneled Donna Karan Atelier gown featuring a chiffon train — and a great view at her toned right butt cheek.

You didn’t think the star would go the whole night without wearing some plunging, sheer Zuhair Murad Couture design, did you? Lopez changed out of her peach princess Elie Saab confection and into something more Jenny from the Block for the Vanity Fair Oscar Party — white fur stole included.

It’s possible that the actress was a flapper in a past life, because she pulls off a drop waist sparkly shift incredibly well. But is her red number (worn to the Vanity Fair Oscars party) better than her chartreuse Elie Saab design from the red carpet? Tough call.

Wearing a dress covered in more than 6,000 pearls (like her custom Calvin Klein collection design) might get a bit tiresome, so Nyong’o decided to change into a glittering, strapless champagne design for the Vanity Fair Oscar Party, which also looks pretty heavy.

We’re not used to seeing a high-low silhouette on the star, but she decided to go for a shorter look, switching from her cleavage-loving custom Givenchy by Riccardo Tisci gown to a flouncy white embellished look at the Vanity Fair Oscar party.
