I was really looking forward to getting this shirt but was kind of disappointed. The shirt is definitely see through. You can see your whole bra and even my tattoo through it. In addition to that the shoulders were too big. Like... the straps did not sit where it looks like they should in the pictures. Maybe I should have gotten a smaller size? Overall, disappointed because the shirt is so cute in the picture. Maybe I'll try again in the black.
I have a striped version of this top from several years ago. Comparing this new version to the old, the new fabric is thinner, showing more details of foundation garments. The white version is fairly translucent. When worn with zero or negative ease, others can see what's underneath. You definitely need nude, seam-free, flat-edged underpinnings with this shirt. I also have the black version.
