This is a great product.  There were no size charts either on Amazon or on the Tion Design website, so I ordered an extra small (I am usually between a size 0 and 2 in tops).  Unfortunately, it was too small and I had to return it.  I was not offered an exchange option, and the price had gone up on Amazon.  I had to pay the return shipping for the lace jacket and then order the sweater from Tion Design directly.  In essence, I paid for shipping 3 times (original shipping, return shipping, and shipping on the size small).  It is a nice product and will work great with the bridesmaid dress I am going to wear, but I am disappointed that I had to pay so much for shipping when there was no way I could have known what size to order without a size chart.  If you are in between sizes or not sure what size to order, I would recommend ordering the larger size.
