Both are sheer, but the differences matter. The Absolute Voile is 100% polyester spun at 96 GSM — lighter, more transparent, and with a simpler synthetic character. The Plain Classic uses a cotton, polyester, viscose blend at 148 GSM — heavier, with better daytime privacy, a more natural hand feel, and a more substantial drape. The Absolute Voile is an excellent choice when you want maximum transparency and lightness. The Plain Classic suits situations where you want a bit more body, a more organic feel, and slightly better privacy — while still being clearly in the sheer category rather than the light-filtering one.
