Emma Watson avoided a wardrobe malfunction at the 'Harry Potter and the Deathly Hallows: Part 1' premiere thanks to a little tape.

The price of beauty?

Stickiness and red, blotchy marks.

That's what Emma Watson endured Thursday at the world premiere of "Harry Potter and the Deathly Hallows: Part 1" in London.

The actress wore a mostly sheer black mini-dress, but the tie in the back apparently wasn't enough to keep the outfit firmly in place.

Watson, 20, instead relied on clear tape to secure the fabric to her skin – and it worked.

Sure, the easy and cheap solution looked a little odd and Watson had red marks after the tape was removed, but a wardrobe malfunction surely would've looked worse.

With the simple fashion fix, the former child star looked worry-free on the red carpet, radiating confidence and offering big grins for photographers and fans alike.
