I will update this review once the product arrives. Wish the shipping was available on Prime instead of by snail mail from China!
Edit: So it finally arrived and my Wife tried it on. Doesn't fit, too small. Even though other reviewers on Amazon said it had good stretch it still wasn't enough for her chest size. She purchased this in an XL since it is the largest they had, which fits 76-80cm breast, but her being 110cm was too much for it. She had boob squishing out all over the place and was uncomfortable. Not the garment's fault, it just wasn't built for someone as ample bosomed as she is.
The material wes decent, definitely not high end lingerie material, but would last for at least a couple of wearings. There is some stretch but not a great amount. The lace feels like it is stitched to the straps with not much care about the strength so bigger chested ladies, take that into consideration if wearing it that the strain on the material will probably cause it to rip soon. Not really any support at all so bouncing will also be a thing.
Would I pay $9.99 again for this if it was available in a bigger size that would fit her? No, I wouldn't. It is more of a quick on and quick off check these out kind of thing and nicer can be had for the same price. Save your money and look for something else unluss you want it just for the wow factor if wearing it so your chest is exposed in something like a button up shirt. Then again, if you are big breasted enough where this wouldn't fit you aren't wearing button up shirts anyway.
Giving this a thumbs down and a hard pass.
