The female DRG AF belly window needs to be closed

If you don't like it, don't wear it. There are plenty of alternative outfits available for Dragoons that covers more and still look "Dragoon" like. I chose Tortisescale on Lin for a long time in her appearances because the aesthetics matched her better. Now I just use whatever gear I feel fits her character more.

I don't feel the need to impose my will on the designers because I have issue for a particular piece of digital clothing.

We have a new set of Dragoon armor coming in the expansion, one that may very well suit your desires. Otherwise, I recommend perhaps using gear like the Demon Mail of Maiming as an alternative. The remaining Dragoon pieces can then be dyed a similar color.
