I prefer vinyl. It has been my fetish since I was 5 years old in 1980. I have in my collection: Gerber Toddlers from the 80s (4 pairs), toddler size Safety 1st from '96 (40+ pairs). In adult size I have yellow Rearz nursery print (2 pairs), Haian black bikini (2 pairs), Haian red bikini (3 pair), Haian blue bikini (1 pair), Haian raindrop bikini (1 pair), Leakmaster white bikini (2 pairs), Leakmaster white full (3 pairs), Priva clear (1 pair), Careactive full clear (2 pairs), DMI white full (1 pair), Quik Sorb white full (1 pair).
I'm making up for lost time when I was unable to afford even one of the listed above.
