A Sainsbury's shopper said she was "livid" after claiming she was "shamed" and told to cover up following complaints over her outfit.

Self-described feminist Lauren O'Connor, 33, was shopping at the Staines supermarket branch when she says a staff member approached her and told her to pull her T-shirt down over her shorts.

Shopping in scorching 32C temperatures on Wednesday, the PR manager was wearing a casual pair of pink jersey shorts and a striped t-shirt as she popped into the store.

The Mirror reports the PR manager claims a member of staff informed her a customer had made a complaint about her outfit.

Sharing her fury over the incident on Twitter, Lauren said: "I am so angry right now.

"Just been approached by a @sainsburys staff member in Staines store to 'pull my t shirt down'.

"An elderly man made comment to staff member who felt compelled to come and and tell me as I was shopping.

"It's 32 degrees. If I want to wear shorts I will."

Sharing an image of her outfit, she added in a series of follow up tweets: "For reference, this is my outfit. All I wanted was ice lollies and I get shamed in store doing so. So disappointed. When are we going to stop telling women how to dress? Especially when topless men frequent supermarkets, which I highly doubt are told to change.

"I'm so livid about it. When are we going to stop giving the space for men who can't stop being perverts? I am so tired of having to defend my existence and love of booty shorts!"

Many social media users were horrified by Lauren's claims.

Another jokingly wrote: "'Please tell me you pulled your shirt all the way down from neckline to waist."

On August 13, Lauren added another tweet where she said: "Have spoken to @sainsburys Staines store Manager. Who has confirmed that the staff member won’t be getting in any kind of trouble over this. Simply ‘reeducating’ (as the manager put it) on conduct. Am waiting on head office in reference to other women’s ignored concerns."

Speaking to FEMAIL, Lauren said she was "mortified" by the incident - which came about as she popped into the shop to buy ice lollies for her mother to cool down in the scorching heat.

She said: "I was at a loss for words that A), someone felt the need to comment on what I was wearing and tell a member of staff.

"And B), that the member of staff told me about it. I was mortified. I was wearing a mask but can you imagine the colour my cheeks would have been."

A spokesperson for Sainsbury's told FEMAIL: "We are speaking to the store to understand what happened and would like to apologise to Lauren for any offence caused."
