Anti-knife crime campaigners have accused Topman of glamorising violence by selling sleeveless jackets which resemble stab-proof vests.
The range of gilets are marketed as 'tactical' vests by the clothing chain. French company Sixth June designed the jackets, which are on sale for between £26 and £55.
Campaigners have criticised Topman – owned by Sir Philip Green's Arcadia group – for selling the clothing amid an epidemic of knife crime.

There were three fatal stabbings in London over the course of about 12 hours on Friday alone. And little more than a week ago, terrorist Usman Khan stabbed two people to death near London Bridge.
Critics include the father of Damilola Taylor, the ten-year-old schoolboy who was fatally stabbed in 2000 in a killing that shocked the nation. Richard Taylor said: 'I am totally disappointed that fashion houses like Topman should be selling such a vest.
'I am totally against it, especially selling it at this critical time and simply to make money. They want young people to buy it.
'They should not be glamorising this culture – we are fighting tooth and nail against knife violence and are mourning the death of two young people last week.'

Anti-knife campaigner Jen Lock, of Lives Instead Of Knives, said: 'It's totally irresponsible. Where do these people come up with these ideas?
'That is feeding off the UK's knife crime epidemic and someone is trying to make money out of it. It's exploiting young people and promoting what the rest of us are trying to discourage or turn people away from.'
Members of the public have also voiced their disgust at the range.
One wrote on social media: 'I can't believe Topman are selling clothing that's designed to look like a stab vest.'
In France, Sixth June describe the gilets as 'imitation bulletproof vests', adding: 'This item is not a professional product and will not protect against bullets.'
Ministry of Justice figures revealed there were 22,306 knife or dangerous weapon offences dealt with in England and Wales in the 12 months to June, up from 21,314 in the same period the previous year.
