It tells the fashion industry that it must take responsibility for the signal it sends women, especially teenage girls, about the social tape – measure they must use to determine their individual worth.
断句：It tells the fashion industry // that it must take responsibility for the signal it sends women, especially teenage girls, about the social tape – measure //they must use to determine their individual worth.
顺译：它还告诉时尚行业。 它必须承担责任 因为信号 它发送给女性，尤其是女青少年，关于社会卷尺。她们一定会用来去决定她们的个人价值。
解析：tell sb sth，所以that it must take responsibility 是宾语从句。for the signa是做原因状语，especially teenage girls, about the social tape – measure,做定语修饰signal，只不过省略了从属连词。they must use to determine their individual worth做第关于修饰social tape – measure。
调整：还警告时尚产业：对于女性该用什么样的社会标尺来判定自己的个人价值这一问题，时尚产业给女性，尤其是未成年少女，传达了错误的信号，时尚产业必须为此负责。
