In various example embodiments, a system and method for authenticating a garment are presented. The authentication system can include a code reader configured to receive an image of a garment. An asymmetrical pattern can be woven in a section of the garment. The code reader can decode weft and warp information from weave lines in the asymmetrical pattern and determine a validation code based on the weft and warp information. Additionally, an authentication system can access, from an authentication database, authentication codes associated with authentic garments. The authentication system can calculate a confidence score based on a comparison of the validation code with one of the authentication codes. Subsequently, a publication system can cause a presentation, on a display of a device, a verification that the garment is authentic when the confidence score is above a predetermined threshold.
