The hot summer and sluggish high street sales have savaged profits at Slimma, the manufacturer which specialises in clothes for larger customers. Profits for the year to September slumped to pounds 33,000 from pounds 1m last year and the dividend has been halved to 1.3p. Margins were lower due to a shift in the sales mix towards supplying more multiple retailers. Mail order sales were also down. The company says it has reduced overheads by selling a smaller factory and is keen to exploit its export business.
