I bought a white and black in the spring when they were made by Additonelle. I ordered 2x (for reference I wear a 36G) and 1x for my daughter(she wears a 32 g or H)). They were perfect. I ordered more when they came back in stock. The 2x in Dessee were the same size as the 1x in Additionelle, so I exchanged them for 3x. Then I saw the grey and blue and bought them in 3x. I had to change them for 2X. They are comfortable and actually supportive. I wear them all the time now. I highly recommend them.
