I don't see the resemblance to pitchittoman. One piece swimsuits are glorious, they accentuate the body without showing much skin along with being significantly distinct from underwear or lingerie.
Though they are harder to draw though in my opinion, as I personally find the reflectivity of one piece swimsuits (especially when wet) to be extremely important in showing off bodily curves, along with how and where certain parts of the fabric are stretched (most often due to hips, butts, and breasts). These aren't traits that bikinis/multi-piece swimsuits often carry, and therefore aren't often traits artists have to worry about.
Well anyway, thanks for the chapter Sappy Snail Scans and Keiretsu.
