Finally got a response from TopShop, they'd just like to confirm they don't actually give a crap about woman and girls and haven't actually answered any of my questions.
*On behalf of Topshop Topman I am sorry to hear that you feel this way and I want to reassure you personally that it is never our intention to cause offence to our valued customers.
We endeavour to provide a shopping experience that is both enjoyable and inclusive for all our customers and as such made a recent decision to update our fitting room guidelines.
As with all decisions, the policy revision to open all fitting rooms to all customers was made with our customers at the forefront of our thinking. We pride ourselves on being inclusive to all and believe our customers should be made to feel as comfortable as possible whilst in our stores.
Our customers are always our highest priority and all our fitting rooms are individual, private spaces – the areas are fully staffed and monitored to ensure the safety and security of our customers.
I trust this email gives you more context around our decision and I hope, in due course, you may decide to shop with us again in the future. Please accept my sincerest apologies for any inconvenience caused.
If there is anything further I can help with, please do not hesitate to contact me by replying to this email address.*
