I now have two of these long-sleeved tops in black, plus two short-sleeved, one longline one not, of the same style - my go-tos for casual wear round the house, walking, etc. They cover the midriff where they need to. As regards sizing, I am usually a 16 in other brands but buy a 14 in this style. Cotton is a must for me. As a caution I have to say the quality, such as the thickness of the material is not always consistent with this brand.
