Owners of an independent t-shirt shop are fuming after PrettyLittleThing "stole" the designs for their bestselling Euro 2024 tops."

Lydia Day and Callum Massey, both 25, designed a collection for the upcoming tournament.

But they were baffled when they found nearly identical copies of two of their tops being sold on PLT.

The shirts - with the phrases 'England here to play, I'm here to slay' and 'Teach me the offside rule' - cost just £10 which is half the price of Lydia and Callum's tops.

They claim the font, the text size, and colour on the original designs are almost identical to the versions on the PLT website.

Lydia, from Liverpool, said: "PLT can offer a much lower price due to buying power and sourcing overseas."

"PLT offering a lower price for a more or less identical product is hurtful to our business because we can't match that as we ethically print in the UK."

"On the PLT website it says how many people have checked out the t-shirt in the last few hours."

"This is potentially sales taken from us - and if the numbers on the screenshot are true, they've sold more in a few hours than we have sold overall." "

The pair started Sis What's The Tee, in October and create products inspired by events such as St Patrick's Day, Pride and football tournaments.

After releasing their football-themed t-shirts in April, priced at £19.95, they were disheartened to receive messages from customers who later saw almost identical products on the PLT website for half the price.

Callum, from Wolverhampton, said: "They must have seen that our designs work, that they're popular, and they probably don't want to waste their time or money experimenting. "

"They want to go with products that already have proven success. They must have seen our designs on TikTok - their tops have the exact same wording. The font is almost exactly the same - it's no coincidence." "

Lydia and Callum posted a TikTok about PLT "stealing" their designs which received lots of support and a boost to their sales. "

One customer commented: "I got my euros top from you guys! And when I saw this on plt I INSTANTLY thought of you guys xx."

Others branded PLT as "lazy" and "desperate", with one TikTok user commenting: "They are running out of ideas". "

Despite the support from their followers, the small business owners said the experience was "intimidating" and Callum added: "It's quite off-putting to be honest. "

"You put in all that work, then see a big brand with more money and more power - who can pile lots more into advertising - just overshadowing small businesses who don't have that same kind of reach."

The pair are the company's two sole employees.

When an order is placed, it is then sent to a UK-based printing service where the product is created and then shipped to the customer.

Callum said this helps reduce potential waste - as products are created on demand and there is no minimum order quantity.

PLT has been contacted for comment.
