• Here are a few options
• depending on the exact nuance you want to convey
• all suitable for South American Spanish: **Option 1 (Most direct and common):** "Alguna que otra **pelotita** y **mancha tenue**
• ligero desgaste en la **pretina elástica**." * **Pelotita:** Common term for fabric bobbles/pilling. * **Mancha tenue:** Faint/light mark or stain. * **Pretina elástica:** Elastic waistband (very common term in South America). **Option 2 (Slightly more formal/detailed):** "Presencia de alguna **motita** o **bolita** y una **marca apenas visible**
• con leve desgaste en el elástico de la cintura." * **Motita/Bolita:** Other terms for fabric bobbles. * **Marca apenas visible:** Mark barely visible. * **Elástico de la cintura:** Elastic of the waistband. **Option 3 (More concise):** "Pequeñas **bolitas** y **mancha ligera**
• leve desgaste en el elástico de la cintura." I'd generally recommend **Option 1** as it's very natural and clear for describing these types of defects on clothing in South America.
