I use to wear suspenders for comfort (I rarely took my suit coat off, so I couldn't say it was for style).
I spent a lot of time flying in my career and to compensate for the bloating caused by flying, I would wear baggy trousers with suspenders. Unbelievably comfortable.
“Sansabelt slacks didn’t come with suspenders.”
Oh, I know. I had several pair of Sansabelt slacks and loved them...so comfortable. Of course, that was when I was slim. When my gut started flowing over the waistline...I parked them in my closet. Sigh...
