Jean Arthur appeared on the cover of the September 1940 issue of Arizona Highways wearing the wedding gown (sans veil). There was also a six-page spread about the film. You can view the entire magazine here! Click the download symbol to view a pdf of the magazine. This is the clearest picture of the gown I could find and it also shows the hem and tiers really well. It could easily look too fussy but somehow doesn't.
This shows the "stripes" on the skirt a little better.
The dress has a scoop neckline with drop shoulders and balloon sleeves.
Another shot. If you're wondering why Jean Arthur doesn't look too happy it's because right after the wedding William Holden has a gunfight scheduled. I have to say, she's taking it much better than I would have ;)
The veil doesn't look historically accurate to me but I love it so much. The lace is exquisite.
She wears it almost as if it were a shawl.
It comes down to a point on the sides.
On most women the bow could look silly but Jean makes it work. Such a pretty curled updo!
Another look at the bow as well as her beaded choker.
Just because ;) *swoon*
