When sourcing honeymoon lingerie, the fabric composition is the most critical factor for both luxury appeal and wearer comfort. Prioritize suppliers using Grade A Mulberry Silk, high-density nylon-spandex blends, or OEKO-TEX Standard 100 certified lace to ensure the product is free from harmful chemicals. For high-end markets, ensure the lace is soft-to-the-touch (anti-itch) and features scalloped edges rather than raw cuts. Additionally, the crotch lining must be 100% cotton for hygiene and breathability, meeting international health standards.
