Tuesday night (July 26), Bill Clinton, the husband of presidential nominee Hillary Clinton, took the stage at the Democratic National Convention to honor his wife’s historic achievement. Bill’s stately-but-approachable appearance and middle-of-the-road fashion choices make him a terrific candidate for the supporting role of first spouse of the United States. (He was also the 42nd president of the United States.)

He may lack current first lady Michelle Obama’s upper arm strength, but he makes up for it with a nice head of hair.

We’ve yet to read an interview with the person who styled Bill’s silver locks for last night’s DNC appearance, or even see a brief in Women’s Wear Daily or GQ crediting the designers who dressed him for the occasion. Did he buy his suit online, like Melania Trump’s Net-a-Porter-purchased Roksanda last week? Did he go to a store? Work directly with a designer? We just don’t know, which means it’s going to be really difficult for this particular navy suit to sell out, as so many of the dresses worn by Michelle Obama have over the past eight years. Was it Hickey Freeman? Hart Schaffner Marx? Again, we just don’t know.

Here’s what we do know: Clinton’s suit was navy blue, and he wore a tonal cobalt tie in a shade similar to the Christian Siriano dress Michelle Obama wore the night before. (Some noted then that the dress matched the stage’s background. Clinton’s tie did too!) The suit had three buttons, a notch lapel, and full-cut trousers that broke substantially over his shiny black dress shoes. One might have even called it a “pantsuit.”

The LA Times’ Adam Tschorn noted that although we don’t know who made this suit, “if you stare at it long enough, a subtle tone-on-tone stripe becomes apparent.” Clinton accessorized with a watch Tschorn identified as a 47mm blue-faced Runwell watch by Shinola—a $550 Detroit-made timepiece. (It’s apparently patriotic enough for Clinton, although the FTC has its doubts.) The potential first gentleman also adorned his lapel with a Hillary campaign button. For jewelry, he wore his wedding ring.

As a fashion moment, it might have been a little underwhelming, but as a historical one, it was not. Clinton’s look stated clearly: I’m with her.

Correction: An earlier version of this post misstated the number of buttons on Bill Clinton’s jacket. It had three buttons, not two.
