Unfortunately, it is not seamless. On the contrary, it has thick seams. Two seams on the sides (one on each side) and one in the front on the cameltoe area. And it is terribly visible and looks very ugly as if you are wearing a pad inside and it shows, the first time I wore it, I lost it. The next time, I wore the underwear with the seam a little more inward, lowering it a bit in the front and lifting it in the back, and luckily it doesn't look like wearing a pad but it forms a cameltoe! It's a shame because it is also expensive underwear. Honestly, if it didn't have this thick seam in the front, it would be perfect. I don't mind the side seams. They should have paid attention to this. Otherwise, from the back, nothing is visible, it is PERFECT.
