Greetings fellow forum fans. I'm new here (as of today) and I have a question about an ongoing clothing quest. I'm looking for a unisex/men's ultra-soft, ultra-thin long sleeve casual shirt (e.g., T-shirt/sweatshirt style pullover). I need a large size and the fabric will likely be that quintessentially soft tri-fabric combination of cotton, polyester, and . . . is it rayon or possibly modal? Anyway, New or used doesn't matter as long as it looks decent and, more importantly, is almost sheer with heavenly feel. I have many cashmere sweaters that meet the softeness criteria but they are too think & overly warm for most uses. Any help you can provide will be much appreciated.
