I m the Romulus single-breasted suit waistcoat. My classicnavy blue fabric has a quality subtle texture and is produced in collaboration with Lyfcycle an ethical, sustainable clothing manufacturer headquartered in the UK. I m a well-fitting, timeless waistcoat made from recycled cloth. My features include five navy blue button fastening, two welt pockets and an adjustable back strap to ensure the perfect fit. I have a bold geo print lining but a plain outer back so when I m without my jacket, I still style well with everything. Dry clean only. 65% Polyester. 35% Viscose.
