This was my second try to find something besides a camisole to wear underneath clothes to achieve a little modesty. I am a 36D and chunky. I ordered a size large, and it fit fine (a tiny bit snug, but I think that's to be expected with a bandeau style). I cannot wear strapless dresses because I am too chunky and the top of the dresses don't lay flat. I had the same problem with this bandeau - it doesn't lay flat across the top close to the arms. This creates an unflattering (and somewhat bizarre)silhouette when clothes are put over it. This bandeau also has the unfortunate combination of creating uni-boob while not fully covering my decolletage, which is as unattractive as it sounds. The picture of the model makes it appear as though the decolletage is fully covered, but this was not my experience.

After trying this, my recommendation is to shop for these products in a store, find something that works well, and then come online to compare prices. Both of my online-only efforts yielded terrible results. This particular product might work for you if your dimensions more closely match the pictured model's. If you can wear strapless dresses without any problems, this may also be a good choice for you.
