This Calvin Klein thong has the crotch liner found in many thongs. The edge is finished with serged sewing. I was trying to get away from that type of insert in thongs, but this thong is soft and comfortable, so I kept it.
There are side seams. Again, the usual in many thongs. Don't care for side seams, but again, soft thong.

The lace is soft, does not feel like lace against my skin. Comfortable thong.
