Thank you for reaching out! We are really glad you were able to return the Fair Trade Shalimar Tunic :)
All of the Sivana Spirit clothing items have their very own custom size chart:)
We get our unique clothing from all over the world and our sizing varies from one item to the next. That is why we take the time to measure all of our items individually and add the measurements to the "custom size chart" per item.
Click on "Size Chart?" This is located under the color swatches and above the sizing buttons. Once you click the "Size Chart?" the size chart will open up for you. It will have body and garment measurements under two different tabs. This is our new updated size chart. It will be really helpful in determining your size :) Hopefully this helps!
