The agony of finding the right size when you go clothes shopping is something that almost all women are very familiar with - as it's quite common to fluctuate between two sizes depending on which shop you're in.
But one woman on TikTok has been left furious after she bought a size 12 pair of trousers from Primark and was completely unable to do them up - despite fitting perfectly into jeans from New Look that were two sizes smaller.
Ally Marie said she had shared a video to social media "to rant" about the problem, as although she is normally a size 10, she had decided to buy a size 12 pair of trousers because they "looked tiny" on the hanger.
