How to make clothes with ps?

First of all, do you mean making completely hand-painted pictures or pictures like PS Taobao?

PS Taobao pictures, that's much easier. Mainly matting.

Open PS, create a new file, and set the picture size to 800x800 pixels (see figure for detailed parameters).

Drag the prepared baby pictures into the PS. Resize the baby pictures so that they are evenly arranged on the page.

Click File-Save the web page and device format, set the parameters, select JPEG as the format (see figure for detailed parameters), and click Save.
