very easily actually. white decals as billay said, Flying Colors Decals Alitalia 777-200 has a good set of them but it will set you back $10USD. it comes with 4 of the swirls, so you can technically build an Alitalia 777 and have 2 left over for whatever project you want
or you can take a toothpick and paint with the tip of that dipping it in white paint.
here is the Flying colors alitalia decals sheet, you can see the swirls under the tail decals
