Many two-piece infant sets use newborn and month-based sizing, commonly listed as newborn, 3 months, 6 months, 9 months, 12 months, 18 months, and 24 months.
Many pull-on bottoms use full or fully encased elastic waistbands. Some garments also feature encased elastic at bottom hems or leg openings for a secure, comfortable fit.
Blends range from 100% cotton to cotton/polyester mixes and cotton with small amounts of spandex. Example blends include 60% cotton/40% polyester, 57% cotton/38% polyester/5% spandex, and 100% cotton interlock.
Many sets are made from cotton or cotton blends (often combined with polyester and small amounts of spandex). Some items are labeled 100% cotton interlock, while others use cotton/polyester blends.
