CEO Brian Brick noted an “encouraging” response to its autumn/winter ranges, but added: “Market conditions remain tough, with a highly competitive retail landscape set to continue.
“There are significant cost headwinds, driven by national living wage, the apprenticeship levy and weaker sterling.
“We are pleased with the performance of Moss Bros during the first half in what was a very tough trading environment.
“We remain acutely aware that market conditions remain tough, with a highly competitive retail landscape set to continue alongside an unpredictable economic back-drop.”
