Look Sandra, I too ordered a lot of stuff I returned. At least shipping one way was free. Why don't you also order a shak, and then just keep the pieces you love. I found the sizing on the shak ran smaller (by that I mean I was a solid small in shak, but medium in mollie) than the other pieces, unless you want to size up to layer a lot under it. I can nicely get a mid-weight small base (ribbie) under my small shak, but for where I live like it best with a small light-weight base (like my kate). My bases are both size small, but the ribbie is more form fitting. If you look at their item descriptions, the ribbie is described as form fit and kate as semi-fit which is accurate.
