There are a few ways to make breasts bigger in Photoshop. One way is to use the “fill” command. This command fills in any white or black pixels that are not currently used by the image. This can help make your breasts look larger than they actually are. Another way to make breasts bigger is to use the “stretch” command. This command stretches out any existing pixels in an image, making them larger and more realistic. Finally, you can use the “fill color” command to create a specific color for your breasts. This will give them a more realistic appearance and help them look larger overall.
