The short black dress joins a higher rounded upper border to exposed arms. A larger open zone remains visible below one arm, continuing towards the back. A narrow waist band separates the closer bodice from the broadly flared short skirt. Both arms are raised with hands behind the head. A narrow dark surface appears beside the rear arm. Feet and shoes are absent from the crop, leaving their actual arrangement unanswered rather than completed through another picture.
Examine the side opening separately from the broader lower shape first. An interesting waist transition need not require that same flared hem. The arm position also changes how much of the side area remains unobstructed. It establishes neither an ordinary moving view nor particular fit on your body.
Request front and side with both arms lowered on the real candidate. Add intended inner layers and inspect that region seated. Your shoes are needed for the complete combination too. Ask about actual connections instead of deriving a confirmed additional function from the narrow side fabric surface. Return to the preferred gap within the whole garment.
