Aitor is a doozy- honestly he could have his own thread, there's a lot to talk about and look at.
From the aesthetic standpoint, aitor advances an extremely modern look and silhouette. it's tempting to call him a futurist, but I think he is grounded in a dystopian look that is more contemporary than anything else-- it evokes the world of akira and ghost in the shell, it evokes the extreme pollution in china, and it evokes the attitudes of modern day riots. it's very slim-- almost like skin tight armor-- and it has military trimmings. his production method is singularly unique in about a dozen ways. it's all built from scratch in his atelier via construction techniques that the man invented. everything is sewn edge to edge with zero seam allowance. i believe he does this by using double layers of fabric everywhere and sewing them together where they meet-- imagine laying two pillow cases flat, sewing them together at the seams and pulling them tight. i could be wrong about this, but i know there is nothing else available that's made the same way. this shit blows my mind: his button holes have NO STITCHING! most of the seams are also taped, not for weatherproofing usually but rather for the look it brings.
conceptually i find him brilliant because while the look is modern and avant garde, it's all rooted in modern events such as racist stop and frisk policies, hurricane katrina, and UK football casuals/hooligans. i recommend you look up his sketches. they are highly stylized yet the relationship between them and his garments is clear. his sketches all depict anatomical forms in movement, and this is evident in his product by the intricate and unique pattern making. you can also see this in his capsule collaboration with soccer brand umbro. this marketing vid for the collab --

his stuff is often lumped in with techwear, and there are obvious similarities between his gear and acronym, veilance, and also BBS, CCP and rick owens (in terms of an obsession with modern or new pattern making). but it's not technical in the traditional sense (which usually means schoeller or gore fabrics with a gusset here or there). the stuff is technical in terms of range of movement, but it's also technical in a largely conceptual sense-- for instance, almost all of his bottoms have shoes engineered into the hem so they can be worn by themselves. but i'm not sure how practical it actually winds up being. his pricing scheme also makes ACR/veilance look like budget options
