This is a Cable & Gauge sleeveless white blouse with tassel tie closure at the neck.  The fabric has some holes in it like an eyelet fabric but it is not the cotton eyelet fabric.  There is also some stitched flowers and 3D little puffs which you can see in the measurement photos better.  The top has been washed so the tassel ties could use a little straightening as shown in photo.  It is 99% polyester and 1% spandex and in good condition.
