The review about this product
This has become my favourite long underwear top.
The material is deceptively lightweight, but it does indeed feel soft and warm without adding bulk. It has a flattering, form fitting shape. The box indicates that a size S/M will fit someone with a UK dress size of 6 to 14 (U.S. equivalent size 4 to 12) and a bust size of 29" to 41". I can state that it fits like a dream on a junior or petite person with a 27" or 28" bust and a 24" waist. The material (63% modal, 35% nylon, and 2% elastane) has quite a bit of stretch to it, so that I can see it fitting the larger measurements in the S/M range as well.
In the dead of Canadian winters, this works very well as a base layer (meaning you will have to wear another top over it to keep comfortably warm). But it looks and feels so good, it is tempting to wear it by itself in spring or early fall. (You might want to wear it around the house, though, because your bra will show through.) Be aware that hand washing in cool water is recommended -- no bleach, no dryer, no dry-cleaning, and (yay) no ironing.
