Petite dresses are mostly cut with a shorter sleeve and have a separate cut for the hip portion, making the curves of a woman look beautiful than ever. If you are a woman who is about 5 feet 4 inches in height, then this type of clothing will give a better fit, irrespective of your body shape.
You can even wear a petite pant along with your petite dresses. Women with short waists might need to wear both of them together. No woman can be uncomfortable with this type of clothing.
