The Black Trousers by Ecko are very similar to the Classic Collection Traditional Black Trousers. They feature the same adjustable waist and double pleated front but they do not include a satin side stripe. This provides a wider range of use because they are appropriate for use with a tuxedo or an everyday suit. Fashioned from tropical worsted wool, these trousers will match any black coat that is also fashioned from tropical worsted wool.
