Buyers should focus on fabric density (thread count) and edge finishing. High-quality stoles typically feature hand-rolled hems, which are a hallmark of premium craftsmanship, whereas machine-stitched or fringed edges are common for casual styles. Ensure the product meets OEKO-TEX Standard 100 to guarantee it is free from harmful AZO dyes, especially since stoles have direct skin contact. For printed stoles, verify the penetration level of the digital print to ensure the design is visible on both sides.
