Motif straps beside visible side areas make an important distinction clear in this picture. The patterned upper areas appear broader, while skin-visible zones remain beside the bodice. A clearly drawn band marks the waist. Larger motifs begin on a quieter skirt area below. One raised arm makes the side line particularly visible. The image therefore shows neighbouring areas as well as the strap, and width cannot answer every coverage question.
Choose the intended shoulder width first. Assess side coverage separately afterwards. You may enjoy the motif shape while seeking a more closed actual version. Try candidates with intended underwear and relax both arms initially. Add reaching and holding an object instead of repeating only the raised pose. Record which boundary appears in each position.
For the waist decision, compare a quieter band where a real version is offered. Visible motifs and skin areas cannot establish fibre or function. Use the reference to describe the relationship between shoulder width, side surface and middle finish more precisely, then confirm it on the actual garment.
