I ordered this top based on the sizing of a previous top I had ordered from the same company. The two tops have a similar style. This top ran much larger so I started with a large and had to return it twice to find the right fit. I was extremely pleased with the customer service. The exchanges were made quickly and postage paid by BBB. I didn't give 5 stars because the sizing was inconsistent. The top I'm keeping has very tight elastic on the bell sleeves. I haven't worn it yet but I'm afraid it's going to be uncomfortably tight. I chose not to send it back as I like it and the rest of the fit is good. BBB is a super company to work with and I will order from them again.
