This is a set of so-classic Trafalgar striped braces or suspenders. Made of woven silk grosgrain 'ribbon', they're dark wine red, gray and navy blue vertical stripes.  Brown leather button tabs at the ends, and brass hardware stamped 'Trafalgar'. 
 
Pre-owned, used; in good overall condition with no noted flaws.
 
Straps measure 1 1/2" wide.
