Bonmarché sales rose 6.5% to £97m for the 26 weeks to September 26 2015, compared with the previous year.
Store sales increased 2% on a like-for-like basis for the period.
However, pre-tax profit for the period fell 15% to £5.4m from £6.4m last year on a pre-exceptional basis.
The value retailer had net cash of £18.6m at the half-year-end, up 48% on 2014.
During the period, Bonmarché appointed a new multichannel and marketing director, and launched a test TV advertising campaign.
It reported overall like-for-like improvement, particularly in coats and knitwear, where it ”deseasonalised” transitional ranges after last year’s mild autumn.
It opened net eight stores and concessions, and is on track to complete the modernisation of 140 fascias by the year end.
Bonmarché launched a fully responsive website in July and rolled out personal shopping.
“Trading conditions during November have been challenging, due to very mild wet weather,” said chief executive Beth Butterwick. “Our expectations for the full year remain unchanged, provided that trading conditions normalise for the remainder of the financial year.”
