Hmmm. I was thinking over the best way to incorporate Nanosuits meant for combat that can also replicate various linen materials (such as for Winds' mage-type outfit), and I think we could make it similar to how the Vision can transmutate his appearance in the MCU, like his cape and outfits in WandaVision. For those of us that don't have a visible helmet, the Nanosuit could form a thin layer over their face and eschew the features, similar to how Vision changes between his human face and synthezoid face. Winds, for yours, you could say that once he first bonds with his suit and sees it's default appearance, he's like, "Oh no, this won't do," and he subconsciously changes it, afterwards being like, "Ah, much better." You could say he is a huge fan of fantasy themes and roleplaying games, and that could be part of his inspiration for the suit. And to insulate him against damage that would normally go right through loose cloth, perhaps it can shift localized density to reinforce certain areas at moments of considerable impact and pressure. 

Also, since the suits should have some kind of HUD in the visor similar to Iron Man, for you Winds, it could be the equivalent of contact lenses or something. They could alter his true eye color so as to mask his identity and also provide visual data on his suit's statistics and anything from scans and sensors and such. 

If you haven't seen it, here's a GIF of Vision changing from his Halloween costume into his full synthezoid form.
