All sorts of ways, as long as you understand that Gimp works in pixels. It is important to start of with an objective in mind.
A few screenshots so not in-line look as required.
You know that you are going to print your design (on a t-shirt?) so you must have some idea of the size required. For this example I use 15 cm x 15 cm.
Create a new canvas like this: https://i.imgur.com/rDyBWsI.jpg
1. File -> New
2. Use the advanced options and set resolution first - I use 300 ppi
3. You can use real-world units, cm here, and enter the required Width and Height 15 x 15 cm
4. Note: there will be some rounding to match the size in pixels shown as 1772 x 1772 pix.
For importing vector and clip-art https://i.imgur.com/3IoJZ5c.jpg
5. File -> Open as Layers
6. Set the required resolution (300 here)
7. Set width or height to suit the canvas size. Canvas size is 1772 pix so I use 1700. You could use cm there as an alternative.

8. File -> Open as Layers
9. There is no choice on size, it is whatever the image is in pixels. It is possible to scale the layer up or down once imported but beware of degradation.

You can check the properties or the print size, but you started with 300 ppi and that is what is used (unless you change it)
Note: anything copied and pasted into the image will automatically use the image 300 ppi.
The reverse is not true. Copy that image and paste into a 96 ppi (usual default ppi) image and the resulting image is 96 ppi
Remember to Save the image as a Gimp .xcf which saves layers, masks, paths etc.
To send to a printer, Export a png, that saves any transparency
