This is a serviceable nursing tank and actually fits me; I wear about a 32H (UK), which means I'm skinny but have huge breasts, and it's hard for me to find shelf-bra tanks that fit. I have this in (I think) a 34 F/G and it works well on me. It is not my favorite product because of two features: first, the band is not adjustable, which means it's a tight elastic band that has to be stretched to fit over (swollen, sensitive) breasts, and this was uncomfortable for me. Second, when the cup is snapped down to nurse, it's held in place by only a thin strap of material to the side, so the entire breast is just flapping there, and I prefer styles that have slings for the breasts. Consequently I reach for my Glamourmom full bust long tank more often, which has these features in the styles I prefer.
The fabric is nice and thick and I think this top will last well. The snap-down clasps are a little tricky to operate.
