I hate wearing bras so I was very happy when firmwear undergarments were created.  This particular brand holds its shape through many wearings and washings (I use the gentle cycle and low heat or handwash) but be aware that the longer style, as pictured here, tends to ride up unless it's held down by pants.  So, if you're wearing this under a skirt, it might pucker and make your stomach look bigger than it is.
