The reality TV personality, 22, has come under fire for the 'offensive' sizing in her Melissajay range, but stood by her decision during an appearance on Wednesday's edition of the Heart Breakfast Show. While the average woman in the UK wears a size 16, the aspiring designer insisted she is 'very small' and wants to 'cater to petite women' with her collection because 'lots of brands' carry larger sizes.

It's just the way that I did it. 'I started off the range as a petite range because I'm a very small and I wanted to cater to that. There are lots of other brands that cater to larger sizes.' During her appearance, presenter Lucy quizzed the reality star on the effect of her labelling on younger children, saying: 'Can you see how people would look at that and maybe feel offended or be bigger than they are? I would say 8-10 is a small.' The brunette was defiant as she responded: 'To me, a size 4-6 is an extra small, do you know what I mean? I was a very small company to start with so I couldn't make a lot of sizes.'
