• Here are a few options
• all suitable for South American Spanish
• with slight variations in phrasing: **Option 1 (Most common and direct):** "Los detalles de la talla se han desvanecido
• con pequeñas manchas en la parte inferior delantera." **Option 2 (Slightly more emphasis on legibility):** "La información de la talla está borrosa/ilegible
• con ligeras marcas en la parte baja delantera." **Option 3 (More concise):** "Talla desvanecida
• con manchas tenues en el frente inferior." **Breakdown of terms:** * **Size details have faded:** * *Los detalles de la talla se han desvanecido* (The details of the size have faded - very common) * *La información de la talla está borrosa/ilegible* (The size information is blurry/illegible - also very common) * *Talla desvanecida* (Faded size - more concise
• like a bullet point) * **Faint marks:** * *Pequeñas manchas* (Small stains/marks - very natural) * *Ligeras marcas* (Light marks) * *Manchas tenues* (Faint/subtle stains) * **To lower front:** * *En la parte inferior delantera* (On the lower front part - standard) * *En la parte baja delantera* (On the low front part - common
• slightly more colloquial) * *En el frente inferior* (On the lower front - more concise) I'd recommend **Option 1** as it's very clear and natural for describing defects on clothing.
