• Here are a few options
• all suitable for South American Spanish
• ranging slightly in formality/conciseness: **Option 1 (Concise and common):** "**Leve decoloración en el cuello y las mangas
• y unas pocas marcas pequeñas en la parte trasera.**" *(Slight discoloration on the collar and sleeves
• and a few small marks on the back.)* **Option 2 (Slightly more descriptive
• using diminutives):** "**Cierta decoloración en el cuello y las mangas
• con unas manchitas diminutas en la espalda.**" *(Certain discoloration on the collar and sleeves
• with a few tiny little marks on the back.)* **Option 3 (Very common
• slightly more informal):** "**Un poco de decoloración en el cuello y las mangas
• y algunas marquitas en la parte de atrás.**" *(A little bit of discoloration on the collar and sleeves
• and some little marks on the back part.)* I'd lean towards **Option 1** or **Option 2** as they are very clear and professional for a defect description.
