There is a similar trend here too mostly with the new emerging brands. Especially on the online store. They make more fashionable items to wear, but their sizes is different from the earlier brands. Their clothing looks attractive and decent, but the size that I often wear doesn't fits and a size above doesn't suit on me. So I gave to be content by mere looking them online. And prefer to buy the old brands that still produces better size and better quality.
