I am under five feet tall and am a US Size 4 with a small chest, so I was actually concerned that a small might end up being too big.  Turned out that it is a perfect fit.  There was actually a moment of concern that it might be too small, but I just needed to get the shelf bra moved to the correct position.

The toning bands do run right along where they show in the picture and are quite firm.  I do not know what the result will be from wearing it while working out yet, but it feels like I am getting a little more work in those areas.  My chest stays firmly in place, so at least for my size there is no need to wear an extra sports bra underneath.  I ordered the Malibu Blue and it is a bright and lovely shade.  It is nice enough that there is no need to wear anything else over it if you are going for a walk or jog and the weather is right.

I also purchased the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Reebok-Women-s-Easytone-Pant/dp/B003XIHUX6/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Reebok Women's Easytone Pant</a>&nbsp;but since I am a little shorter (okay, a lot shorter) than average I will not be able to do an adequate review of these until I get them back from alternations.
