Tarzan can do more than just swing from jungle vines — he can zip up dresses too!
The blonde beauty stunned with side boob in a custom silver Miu Miu gown with keyhole cut-out, but unfortunately the zipper of the bespoke number wasn't quite up to snuff.
Alex came to the rescue, and it was such a cute moment between the two! Too bad Margot has a boyfriend because we'd totally ship her with A.Skars.
Honestly? We'd deliberately mess up our outfit so Tarzan could come help us fix it.
Smart move, Margot!
