Hi Glen, Yes-there is some play and I can certainly move it upwards to cover more of the armor gaps and closer to the cover strip. I purposely did not glue it yet just in case there was some feedback like this!
Yes I think the chest could come up a touch, will be easier to manage once you have the shoulder straps attached.
Note the gap between the ab plate and chest
The gap on Luke was a lot closer due to his height
