It’s because she had those incredible boobs to fill it out!

The multi-colored mini-dress worn by Jenna (Jennifer Garner) during a pivotal scene in 13 Going on 30 (the magazine party where she performs the “Thriller” dance to liven things up) is apparently lost forever.

Thank gosh for dupes.

The dress, an early-aughts Versace that was only produced in a limited batch, ended up in a warehouse after filming wrapped, and was eventually tossed. At least, that’s what costume designer Susie DeSanto assumes.

“I sadly think it’s in a landfill somewhere,” she told People to commemorate the movie’s 20th anniversary. DeSanto says that neither she nor Garner took the dress home, though she doesn’t remember why not. She observed that if the OG garment were out there anywhere, someone probably would have found it by now.

The instantly recognizable garment has, however, been copied to hell and back, and you can get a pretty good facsimile on Amazon for $20, should you care to dress as Jenna for Halloween (or just want to wear it out).

Or, if you’re Ariana Grande, you can ask Donatella Versace for a real one.
