This body type scores points with narrow shoulders and slim legs.
As body type O it is necessary to draw attention away from the pronounced middle section and balance out your proportions. Contemporary casual styles are great for your body type.
Avoid supple smooth fabrics. Current blouse tops in a material mix made of blouse fabric at the front and jersey at the back are perfect for you.
Distinctive patterns and details should be restricted to the shoulder and cleavage areas. For the waist and stomach it would be best to stick to more muted colours. Your legs would also look great with an eye-catching pattern or bright colours.
