Small on the front. Bold on the back.
The sample combines small chest and trouser lettering with a larger back graphic. The dot pattern runs through both garments, so the repeat and the lettering need to work together rather than compete for space.
For your version, send the repeat artwork and placement graphics separately, with dimensions for each. Check the back lettering below the hood, not just on a flat artwork file: the hood will sit over part of the upper back when worn.
Print method, ink finish and wash performance should be agreed on the selected fabric and checked on the sample. The photographs alone do not establish those specifications.
