Marks & Spencer today announced it has made three new design appointments to strengthen its design team.

Head of creative trends at Debenhams, Jeremy Armstrong, has been appointed head of menswear design, while Barbara Calderwood, head of research and development at Hasbro, has been appointed head of childrenswear design.

At Debenhams, Mr Armstrong was responsible for the identification of trend information, research and development of new business opportunities and the management of internal brands.

Prior to joining Debenhams, Mr Armstrong worked as a freelance menswear designer, working for an extensive client list, including Daniel Hechter menswear.

He joins another recent recruit in the menswear design team - Sherri Fried, who has worked for Ralph Lauren and Calvin Klein in the US and Blanc Bleu in Paris.

Ms Calderwood has extensive knowledge and experience in the children's market and has a proven track record in translating concepts into best-selling brands.
