The reason why Sistar was really successful with the four of them was because there was perfect balance with this group. Soyou and Hyolyn are both powerhouses when it comes to vocals and the 2 of them can pretty much keep up with each other. Bora the Main Dancer, rapper and face of the group always captivates us with her on stage charms... Last but not the least Dasum Visual of the group with perfect skin, decent vocals and dance skills and maeknae of the group. The four of them was the "perfect mix".
