I had to size up from my normal medium to a large in order to by comfortable. If you have a bust larger than a B cup, your regular size may not be able to accommodate everything. I ordered 2 sizes just to see which fit I liked better since I saw that the reviews mentioned this top running small. BUT the large is still so flattering on me so I would definitely recommend this top for the pockets and the shape. Also, the tencel material fades even after I followed the wash instructions, so I may try out the fysel material next time. Mediclo please make the Amelia top in Fysel!!
