Sizes are **********ly incorrect

Can you please tell me what's the deal with Mr Price's sizes? Are you guys aware that there are standard sizes to adhere to? I have to buy different sizes for various types of clothes because they're never the same. I bought two different colour skirts but both have the same cuts. They have the same size tag but one is smaller than the other which was strange. Today I bought a pair of shorts that's a size 30 but it's not a size 30. It's the tiniest size 30 I've ever come across. It looks like a size 26. So I want to find out if you guys are having problems because this is not the first time I've had to exchange clothes because the sizing was incorrect. This is a serious problem. Fix your sizes! A size 30 is for someone who has a size 30 waist. You can't just make it smaller or bigger.
