Being forced to wear high heels at work can leave women suffering physical damage more commonly associated with sports injuries, MPs have heard.
Such dress codes strike many women as "humiliating and demeaning" - and can also have serious health consequences, the debate in Parliament was told.
Labour MP Gill Furniss said her own daughter had suffered a metatarsal fracture - the same injury that threatened to put David Beckham out of the 2002 World Cup - as a result of being ordered to wear heels.
The debate was triggered after more than 150,000 people signed a petition calling on ministers to outlaw discriminatory workplace dress codes.
London receptionist Nicola Thorp launched the petition after she was sent home from work when she refused to wear high heels.
Some women were left in tears from their painful and bleeding feet as a result of high heels policies enforced by their employers, heard the debate by the Petitions Committee and Women and Equalities Committee.
Other workers said they had been ordered to undo extra buttons on their blouses to make sales or even told they had to travel to work in full make up or face the sack, said Labour MP Helen Jones.
She said they had heard evidence of "discriminatory" and "totally reprehensible" attitudes towards women.
The debate that equality law should protect women from being subject to rules which are completely out of proportion to those imposed on men.
But tribunal fees of up to £1,200 has prevented many people from seeking justice, the debate heard.
Equalities minister Caroline Dinenage called on all employers to review their dress codes to reform any offices still retaining a "dodgy 1970s workplace diktat".
"I must reiterate that the Government utterly condemns such dress requirements where their effects are discriminatory."
