Purchased in March 2025, only tried on. It's a size M, but it's a large fit. Even though I usually wear L tops, this was still roomy. Recommended for those who prefer a neckline that isn't too tight. Made of thin, 100% cotton. The color is a fluorescent white, or perhaps a bluish white, which doesn't suit my skin tone, so I'm selling it. Will be folded small and shipped via Nekopos.
