I bought this pencil skirt from Simply Be in a US Size 28, and I wear it all the time. I love it, it is fun and flirty, and get compliments whereever I wear it (they no longer have it in this size, but here is a precious, even less expensive, pink lips skirt that is similar.) I had wanted to see what Simply Be sizing was like in this style.
In the last several years I have made several Joe Brown purchases, also from Simply Be. They are cute and fun and fit as well in the US Size 28, and they have worked well on me.
