Translate the following passage into English.不久前，我在上海展览馆看了一场特别的服装表演。“模特儿"都已人到中年甚至老年，从42岁直至74岁。她们穿着自己设计裁剪的服装，随着迪斯科音乐，迈着没有经过训练的朴素的步子，面带羞怯而勇敢的微笑，走在长长的红色地毯上。她们逐渐镇定下来，有了自信，脚步渐渐合拍，并开始注意面对观众。

NOT LONG AGO I SAW A UNIQUE FASHION SHOW AT THE SHANGHAI EXHIBITION HALL. THE "MODELS" WERE ALL OF MIDDLE AGE OR EVEN OLDER, RANGING FROM 42 TO 74. DRESSED IN THE CLOTHES OF THEIR OWN DESIGN AND MAKING AND WEARING A SHY YET BOLD SMILE, THEY WALKED ON A LONG, RED CARPET WITH NATURAL UNTRAINED STEPS TO THE ACCOMPANIMENT OF DISCO MUSIC. GRADUALLY THEY CALMED DOWN AND RESTORED SELF-CONFIDENCE. THEN THEY BEGAN TO MATCH STEPS WITH THE MUSIC AND BECAME AWARE OF THE AUDIENCE.
