Shorts

Most versions of William Branham's stage persona preached strongly against men, women, and children wearing shorts. According to Branham, men who wore shorts were wearing "women's underneath garments", and were "sissies".

She took off the clothes that God dressed her in, back in Eden, for her journey through the--this wilderness. She took them off. She stripped herself down. When, God had her wrapped all over in skins; she's begin to shave a little off each time, now she is back to where she was at the beginning. Now she has got her Adam to wearing her underneath clothes. A man put on them little old sissy-looking shorts, and get out here, I don't think there is much man to him. He is the biggest sissy I know of. See? See, she has got her perverted Adam to act like she, see, wearing her underneath clothes. She seen what she could do out yonder when she took off all of her clothes but her underneath ones. That's the shorts. Course, that's the woman's underneath clothes, and here her Adam is wearing them now. Which, according to God's original Word, "Is an abomination for a woman to put on a garment that pertains to a man, and a man to put on a garment pertains to a woman," from the original Word. Think of it!

Offstage, however, William Branham wore shorts. According to Rebekah Branham Smith, William Branham's daughter, certain "brothers" asked William Branham to wear shorts for a photograph in Africa. Upon further examination of the photo, however, it appears that William Branham's legs are already tanned.

This was in South Africa, at the Kruger National Park and when he was down there I believe it was 1951 and the brothers took him [William Branham] there and talked him into putting on one of these safari suits and had his picture made to bring home to us kids and when we saw it, we said, "That's not Daddy! That's not Daddy!" but you know the Stetson, the Florsheim shoes, they give it way. That's Dad.
