This is my first Greta since the fit changes a few years ago - the new is a lot better and more true to size. The old ones were tiny and VERY cropped. This new Greta just suits perfectly my 5ft3 frame - ideal for high-waisted bottoms. I'm a UK10/34B and the Small is comfortable. For a looser fit, I'd recommend sizing up. The Hawaiian Blue is a vibrant colour and a great match for some of my yaks!
