John Stamos has had our attention for a long time when it comes to his good looks and dapper style. But it's a photo of the actor from long ago — before "Full House," even before his "General Hospital" days — that has us doing a double take today.

The star shared a vintage prom pic with fans on Instagram and ... well, have mercy!

Stamos, then a teen, was decked out in a white tux — complete with a red-trimmed and ruffled shirt and a jumbo bow tie — and his hair was a work of feathered art.

"#TBT #Prom #Hair," Stamos wrote in the caption accompanying the photo.

"I know everybody says this, but in high school, I really was the dorky kid," Stamos revealed in an interview with Orange Coast last year. "I was into magic and theme parks. I was very innocent. When a lot of kids my age were going out drinking on Friday and Saturday nights, I was at Disneyland, going on the rides and listening to the bands."

And keeping that late '70s/early '80s hairdo combed to perfection, no doubt!
