The goal of the research is to compare female preteen pants patterns in different methods. Three methods System Muller & Sohn (M I), Winifred Aldrich (M II) and Natalie Bray (M III) are examined in the research in which exemplification way is used. The comparisons are made with three different basic pants patterns which were prepared for a 152-sized Turkish girl. Compared to the body measurement, the body rise in M I and waist to knee in M II and M III are found much more. M I does not provide the essential additions for hips. It is determined that back grain line slides towards side seam between waist and hips in M III. Sigma CD in MI is shorter than the others. Sigma CW in M II is near to the each other. It is proved at the end that M II has got more necessary qualifications when compared with the others.
