Louisa jumper from Yarn Forward features a deep v-neck with cables either side. Also features a big cable on the front and smaller cables around the armholes. Would also work perfectly as a tank top. Knit pattern as in magazine but leave out the sleeves.

Errata:
On the top of the sleeves the decreases should be: k1, ssk, k until last 3 sts, k2tog, k1.
