Ahead of her holiday to Paris, Beth Whitehouse, 22, decided to take to the Pretty Little Thing website to buy some new clothes for her upcoming trip.
After seeing what she believed to be a figure-hugging, mustard coloured dress she quickly added the £25 dress to her basket.
However, when it arrived just days later Beth was left shocked after she received what she claims was a 'high-vis tent'-like dress.
Beth, from Wolverhampton, has since returned the item to Pretty Little Thing for a refund.
She said: "I bought the outfit because I go on holiday soon, and I thought it would look really nice with boots and tights.
"But when it arrived it looked completely different to the photo - it was as bright as a high-vis jacket and wouldn't tighten up so it was like a tent!
"I couldn't believe the colour mainly - as in the photo it looked like a mustard yellow sort of colour, but it was just blindingly bright.
"I sent it back straight away, I couldn't be wearing that no chance!"
Despite initially being miffed about her order, Beth explains that she has since refunded the dress and can now see the funny side in the order.
She said: "At first, I was annoyed because I was really excited to see the dress.
"But I just decided to refund it, as it wasn't to my taste at all.
"I had to take the photo of it on, because it did look absolutely hilarious in comparison to how it looked on the model.
"Me and my friends can't stop laughing every time we see the photo it's just ridiculous!"
