This is a thin, double-layered garment, so there's no need to worry about transparency (*μ_μ)♪ Made of cotton, it's also great for those who prefer a natural style♪ I wore this when I was in the first and second grades of elementary school ★ミ I mostly wore T-shirts, and I only used this a few times on weekends, so it's in good condition. It's a used item ★ミ Please note that this item has been stored and packaged by an amateur ★ミ Please refrain from purchasing if you are overly concerned about details (*μ_μ) No pets, non-smoker.
