Disclosed in embodiments of the present disclosure are a method and apparatus for virtual fitting. A specific implementation of the method comprises: receiving a fitting request comprising a model picture and a user image; performing human body positioning and surface coordinate analysis on the model picture and the user image respectively; performing clothing segmentation on the model picture and the user image respectively; on the basis of the clothing segmentation result and the surface coordinate analysis result, covering the pixels corresponding to a piece of clothing in the model picture to corresponding positions in the user image to obtain a synthesized image and information to be completed; and inputting the synthesized image, the positioning result of the user image, and said information into a pre-trained image completion network to obtain a completed image.
