This is, says Soucy, "A simple-to-knit basic T shirt with waist shaping, knitted in a DK weight yarn for comfort on its own, or as a light layer under a jacket for work. Yarn shown is Linsey by Berroco. As always, (the design looks) plain or fancy, depending on the yarn used." The depth of the V neck here is perfectly judged for layering. And the look is quite perfect no matter what your shape. If you are weasel-waisted like the lovely young model, by all means knit something very close to your bust size; if not, just build in a little more ease and you will still look sleek and professional.
