1. A method of determining measurements for custom clothing manufacture, comprising: receiving a raw image of a clothing article and a scale reference; recognizing the scale reference; using the scale reference and a hardware processor, applying perspective correction to adjust the raw image and produce an adjusted image; determining a scale of the adjusted image from the scale reference for use with a line measurement tool; causing display of the adjusted image and the line measurement tool on a user display; receiving a user input that positions ends of the line measurement tool on measurement reference positions on the adjusted image of the clothing article; generating a clothing article distance between the measurement reference positions on the adjusted image of the clothing article using the line measurement tool; repeating the receiving user input and the clothing article distance generating steps n times to generate at least n+1 clothing article distances, n being an integer equal to at least 3; and storing the at least n+1 clothing article distances for use in producing a custom clothing article with a fit based on the clothing article in the raw image.
