The t-shirts were designed by Look readers Grace Morgan and Harriet Fox, who were joint winners of a New Look-hosted competition to celebrate the launch of the chain's Design of the Decades range.
The Design of the Decades range reflects styles of clothing from the last 50 years -- spanning the sixties to the noughties. Morgan and Fox each designed a T-shirt to represent 2010.
Barbara Horspool, New Look's group design director, said: "New Look and Look wanted to open up a creative platform for Look's readers where they could explore what inspires them through the medium of music through the decades.
"The winning designs will sit perfectly in New Look, as they exemplify our unique mix of fashion, excitement and fun."
The winners will appear in an issue of Look, receive £500 of New Look vouchers and spend a day shadowing the retailer's buyers and designers, watching their T-shirts being created and delivered to stores.
One quarter of sales of the t-shirts, which go on sale from July 27, will be donated to Jo's Trust, which this year is celebrating its 10th anniversary.
According to the latest Audit Bureau of Circulations figures, Look's circulation, for the period July to December 2008, was 314,329 -- a period-on-period increase of 2.3% and year-on-year hike of 2.9%.
