I only recently found these great tanks, after I decided that sometimes my tummy was yummy enough, and I didn't need shaping so much as smoothing with some outfits. These are perfect for that! They are long enough to tuck, and don't have those bumpy adjustment things in the back (the straps aren't adjustable). And like that they're basically reversible even though where the V Comes together can tickle.
This is a great cut and is a good material, but like most cami's it doesn't stay put very well. I am average in size (8) and I don't have a flat waist, but it's not a washboard either and it just wants to ride up on me.
