Online fashion sales are poised to grow 23% in the UK during 2009, despite projected declines in core apparel sectors, according to new research from Mintel.

The updated market forecasts - which take into account the dramatic economic decline over the past six months - conclude that many sectors of industry will still grow in spite of the recession.

Mintel concludes that about 37% of more than 400 sectors analysed will register growth, led by online fashion with a projected growth rate of 23%.

However, general women's wear sales are forecast to decline 2.3%, while men's wear sales will fall 1.2%.

Designer clothing (projected to fall 3%) and jeans (down 2.4%) will also suffer as consumers buy less or switch to replacement purchases.

"These figures confirm that affordability will take precedence over lifestyle in 2009 as we further feel the impact of the current economic climate," said Richard Perks, director of retail research at Mintel.

"While the trend of trading down will have a negative effect for many consumer sectors, other sectors are benefiting as British consumers change direction and adapt their lifestyle choices accordingly."
