Generate virtual apparel try-on images from a request or supplied person and clothing references. Use when the user asks to virtually try on clothing, change an outfit, dress a person in a provided garment, replace clothing in a photo, or preview a garment on a model. Do not use for generic fashion imagery, ecommerce product placement, or product catalog visuals. Do not use for general photo edits without an outfit change (object removal, background swap, retouch, restyle).
