Amazon EssentialsWomen's Classic-Fit Short-Sleeve V-Neck T-Shirt, Pack of 2, Olive/Black, Medium

Are they made out cotton? do they shrink and lose their shape after washing? do they come smaller than expected? i usually wear l or xl.

To amazon essentials, any chance of these being made in plus sizes? (1x, 2x, 3x) just for the record, xxl is not the same as 2x. trust me.

What is the length in inches from neck to bottom (in back of shirt) for size large? Thanks much if anyone is willing to answer.

Are they stretchh enough and deep enough v neck to breastfeed in them?
