I'm not completely sure but most of the mat groups of V4 and her bodysuit are matching. So it should not be a great problem to use the materials for the suit or as an second skin. Though the original arms and legs material is a bit transparent, I have done the same to my material. This naturally can make a difference in using on the bodysuit or as second skin.

If I'm in some day's satisfied with all materials I make a ZIP of them, including also the morphs for the hair ... seems I have to build some INJ-files, let's see ...

Might be I come also with some morphed boots ... in original they have a diagonal top form as know from wonderwoman boots. So there are some trans maps to do so ... I'm in process ... between my customers silly database programming requests (kind of  "we don't know what we need, but what we get we don't like" :cursing: )

Ok, a separat belt makes sense ... besides shoes and so on one can ever need such accessories for the girls ...
As far as I remember the only props at the belt was something like a cigarett box left of the buckle and something that looks like cartridges on old western belts on the right side.
At the back ... I don't know, it's seldom to show actors in film and tv from the back for long time as ever done ...

There have been definitivly no holster or rayguns in the series. The only gun(s) I remember was that from Commander Straker and his commanding crewmen and that was really normal pistols with an incredible futuristic looking silver sound absorber.
But this is declared by the story ... S.H.A.D.O. was a organisation to defend against aliens coming with that conic flying saucers like UFO's have to be :biggrin:
The defense against them was done with interstellar (moonbase)  or earthbased (sky one) fighters. So the only weapons in contact with the aliens has been the rockets and guns from that vessels.
Except 2 or 3 episodes it gave never any direct contact with the aliens. So Straker's pistol was mainly a attribute to be the chief and used in conflicts with very earthy enemies like upset personal or one times the commanding general.

So no need for complicated gun's and their holsters at the belt. Also the belt needs not to be wearable over a spacesuit. All the technics as futuristic at the time of the series but all is now common or could be build with existing technics. Will say far as it is impossible now to use a normal clothing belt over a spacesuit it was in the series also not foreseen. Better to design the belt as a normal clothing item that could also used for a opera visit than for a battlefight in the space night

B.t.w. your suit with the side cording looks very well ... execpt that the side strings looks a little bit thin, might be only visual. But these strings are foreseen for rough day-by-day work and not like lace on a nighty dessous, so could be a bit more robust I think ...

If you need more ideas have a look on  http://ufoseries.com/index.html . There is also in the image section a blue print of the moonbase outfit showing the backside. Not super detailed but good for the back style of the silver suite.
