Cotton twill is a frequent fabric choice for menâs casual pants in particular. Brands like Dockers have long made use of twill to produce popular menâs chinos, which tend to be both light and comfortable, offering a dressier, but still comfortable change from denim.

Small for gestational age means that a fetus or an infant is smaller or less developed than normal for the baby's gender and gestational age. Gestational age is the age of a fetus or baby that starts on the first day of the mother's last menstrual period.
These markers are used to measure the gestational sac and the length between the crown (head) and rump. If the ultrasound is performed after the 6th week gestation, the length of the fetus from crown to rump is added to 6 weeks to determine gestational age. For instance, if the crown rump measurement is 21 mm, the gestational age of the fetus is 9 weeks. (6 weeks plus 21 days = 9 weeks.) If an ultrasound is performed before the 6th week gestation, age is determined based on other factors, including size of the fetus and development of the gestational sac.
