I believe Yours Clothing do a petite range. They go up to a size 32. So plenty of scope for you. Also try Ann Harvey. Our local shop has closed but you can buy on line.
Does anyone have knowledge of a good place to shop for clothing which isn't meant for a size 6 who is 6' tall I am 5' size 16/18 top and 12/14 bottom(s), and find it extremely difficult to find fashionable clothing, I spend hours on the internet and the high st. I am going on a cruise shortly, and would love to feel well dressed.
