Promising reviews: “Cute top. The fabric is thick (almost sweater thickness). Length is enough to tuck into pants a little, but definitely not long. My one complaint is that the knot in the front makes a gap where the fabric twists. I got this in black so I just make sure to wear a black strapless bra with it to minimize how noticeable the holes are. I’ve washed it several times, and it seems to hold up well. Came out of the wash looking just like it went in!” —akbopper
“True to size and perfect length. The color is the pure white I wanted, and looks great with denim. The knit is soft, comfortable, thick, and stretchy, so it’s not see-through. Length works great with my low-rise jeans or can be tucked in for higher rises.” —Cina
