This study intends to use the basic patterns in 3oz bodice and 2oz sleeve padded jackets made for women in their 20s to research the proper ease of 2oz bodice and 2oz sleeve, 4oz bodice and 3oz sleeve padded jackets. The study also proposes a method of designing padded jacket patterns according to padding thickness. The results of this study are as follows: The 2oz bodice and 2oz sleeve padded jackets had the following sizes. The front and back bust, waist, and hip circumferences were calculated as B/4+2.5cm and B/4+3cm, W/4+2.6+3.3(D)cm and W/4+1.5+2.6(D)cm, and H/4+2.8cm and H/4+3cm, respectively. The length of the jacket was 62.4cm, and the sleeve length was calculated as 63.4cm. For the 4oz bodice and 3oz sleeve padded jackets, the front and back bust, waist, and hip circumferences were calculated as B/4+4cm and B/4+4cm, W/4+4.1+3(D)cm and W/4+2.5+3.6(D)cm, and H/4+4.3cm and H/4+4cm, respectively. The length of the jacket was 63.2cm, and the sleeve length was calculated as 64.2cm. The results of this study showed that padded jackets with thicker padding need more ease. For jackets with stitches, the decreased lengths must be added in the pattern length. The 2oz bodice and 2oz sleeve, 4oz bodice and 3oz sleeve padded jackets all scored 4 points or higher in the movement functionality assessment, thus showing outstanding movement functionality.
