• Here are a few options
• all suitable for South American Spanish
• ranging slightly in formality/conciseness: **Option 1 (Most common and direct):** "Falta el botón del cuello
• mancha leve en el centro de la espalda." **Option 2 (Slightly more descriptive for the mark):** "El botón del cuello está ausente
• pequeña mancha tenue en la parte media trasera." **Option 3 (Very concise):** "Botón del cuello faltante
• marca tenue en la mitad de la espalda." **Breakdown of terms:** * **Collar button has been removed:** * "Falta el botón del cuello" (The collar button is missing) - Very common. * "El botón del cuello está ausente" (The collar button is absent) * "El botón del cuello se ha desprendido" (The collar button has come off) * "Botón del cuello faltante" (Missing collar button) * **Faint mark:** * "Mancha leve" (Light/faint stain) * "Mancha tenue" (Faint/subtle stain) * "Pequeña marca" (Small mark) * "Ligera marca" (Slight mark) * **To mid reverse:** * "En el centro de la espalda" (In the center of the back) - Most natural for a shirt. * "En la parte media trasera" (On the middle back part) * "En la mitad de la espalda" (In the middle of the back) I'd personally lean towards **Option 1** as it's clear
• natural
• and commonly used in defect descriptions.
