I ALWAYS wear tank tops under my shirts. I have trouble finding thin lacey tank tops that are long enough not to roll up when I raise my arms. I bought 5 tank tops in a 3XL, I wear size 20-22 in tops depending on the boobage situation. These tanks are the bomb!!! Wore one to yoga today which was a whole hour of stretching, twisting and moving and the tank stayed in place. Also I have a large chest and I found that the lace at the top does a nice job of covering excess boob. Very happy, layered a different tank top under a pretty foral shirt thats a touch too small in the chest area and it works great. It is a bit see through so just make sure to wear a tan bra if you're wearing it by itself. Definitely plan on buying more when these wear out. Took a few pics to show length and coverage for plus size.
