I am good at designing and making women’s clothes. In my childhood, I spent a lot of time on my grandmother’s home. She used to being a dressmaker, and at that time I was greatly impressed by her job. They seemed magical when a piece of clothes turned into a beautiful dress, skirt, or blouse. So in my adolescence, I begin to learn how to design women’s clothing from an extremely creative teacher. For me, designing women’s clothing is very interesting and exciting. I like the process of creation very well because I feel even if I were an artist. My the first model is my mother, she always gets a lot of praise when wearing the clothes I have made. In a word, she is very proud for me.
