Posting a video on Instagram Kim showed off the custom corset and thigh-length Spanx by French corsetiere, Mr. Pearl which helped her achieve her clinched-in waist.
Kim told fans her gown was so tight she couldn’t even sit down and had to stand in the back of a van and hold onto a pole to make her red carpet arrival.
The television personality, 38, had been following a strict diet and exercise regime so her figure looked jaw-dropping in the gold skin-tight beaded silicone dress.
However Kim revealed she could not be at the table ‘for dinner’ because her uber-tight silhouette would only allow her to ‘half sit’.
She also revealed she was transported to the prestigious event in a sprinter van with a pole installed for her to hold on too.
Addressing Met Gala chairwoman Anna Wintour, Kim, who was wearing her corset. said: ‘OK, so Anna, if I don’t sit down for dinner, now you know why. I’ll be walking around mingling, talking, but I can hardly sit. I can only like, half sit.
