• Here are a few options
• all commonly understood in South American Spanish: **Option 1 (Most common and direct):** "**Leve marca en la parte superior delantera
• con algunas bolitas en toda la prenda.**" * "Leve marca": Light mark/stain * "en la parte superior delantera": to the upper front * "con algunas bolitas": with some bobbling/pilling (literally "small balls") * "en toda la prenda": throughout the garment **Option 2 (Slightly more formal for "bobbling"):** "**Pequeña marca en la parte superior frontal
• con algo de *pilling* (o 'formación de bolitas') generalizado.**" * "Pequeña marca": Small mark * "parte superior frontal": upper front part * "*pilling* (o 'formación de bolitas')": *pilling* (or 'formation of small balls') - *pilling* is sometimes used directly
• but "formación de bolitas" clarifies it. * "generalizado": generalized/throughout **Option 3 (More concise):** "**Marca ligera en el frente superior
• con bolitas por toda la camiseta.**" * "Marca ligera": Light mark * "en el frente superior": on the upper front * "con bolitas por toda la camiseta": with bobbling throughout the shirt I'd recommend **Option 1** as it's very clear and uses the most common terminology.
