Ribbed V-neck sweater-dress

Purchased the black on sale. I assumed it would be a thin, flimsy knit due to time of year. It's actually a nice midweight, super stretchy knit that holds you in. I purchased a medium. I'm usually an M in knits, and an L in wovens without stretch, and bottoms. The M for me is like skin tight, but works b/c like I said it holds you in, and is super stretchy. But I could have done an L, too.
