My fiance is looking for his tuxedo for the wedding and we've settled on a bowtie and cumberbund for his al fit instead of wearing a vest. This is the very first time I've heard of the word cumberbund and it's quite a fun word. If you want to know how it looks like, see image of the one I took. He's not wearing suspenders with his al fit, just a bowtie and cumberbund. I think it's actually spelt like cummerbund. The guy wears it around the waist.
