About a week or 2 ago, I tried on Secret's Comfy Top style [style #5530]. I was very pleased with how it felt. I did not wash it ahead of time. It seemed a bit rougher than I would have wanted, but I definitely still found them very pleasurable to touch. So, you can imagine how good it will feel after it gets its first washing. I have a feeling that it will be great.
Read the remainder of the blog entry for more specific details.
I took a closer look at the top. It turns out that they doubled up the entire panty portion, so you end up getting 2 thick layers. The only seams are the standard vertical seam, and the joining at the leg. Before I tossed them into the laundry, I tried it without underwear, because of how thick it was. It felt just great on its own. I think that each person would have a different preference, because each of us is a different size.
For sizing, I'm about 125 lbs, and 5'6", and I wore a size C.
I tried searching on-line, so that you can see it for yourself, but I could not find a single on-line store that sells them. I purchased mine at The Bay.
I definitely recommend this.
