Who needs a tailor when you’ve got TikTok?

Cardi B turned to a social media trick when it came to taking in a too-big dress, sharing a video clip on Twitter of herself on a plane as her makeup artist and publicist used a hair tie to ingeniously alter her shiny silver outfit.

The “WAP” singer, 30, wrote, “So my stylist wasn’t on the plane with me so Patience and my makeup artist did this TikTok hack to take my dress in… would you try this??? Teamwork make the dream work!!!”

In the video, Cardi appears to be standing in the bathroom of a private plane, facing the mirror and covering her breasts with her hands as her makeup artist sits behind her and folds down the back of her metallic silver dress.

The makeup pro makes a knot in the fabric, wrapping a hair elastic around it several times before flipping the material over and having the rapper pull the straps up.

Cardi B — who wears her hair in a voluminous curly style in the clip — turns around to check out the results, exclaiming “Wow!” as she admires her taken-in dress in the mirror.

The “Bongos” singer then turns to show the final look — and shake her booty in the process— with the fabric now puckered in a ruched detail in the back thanks to the knot on the inside of the dress.

Fans jumped in to praise the “Bodak Yellow” singer on her ingenuity, with one writing, “She did a great job” before posting a second tweet reading, “I’ll definitely try this.

“Fashion icon even in the air” a Cardi B fan account added.

The singer definitely knows a thing or two about keeping her fashion interesting, wearing a silver dress made out of hair clips to the 2023 VMAs last month before partying in a sheer outfit covered with pearls and safety pins a few days later.

Just add a rubber band to her list of go-to dress accessories.
