A lot of space technology is purely functional, but these clearly have poor design taste put into them. The old suits that the Apollo era used were probably almost only functional, yet even they look better.
I think it's hard to make the suits look sleek and cool if only because you need to fit many layers of insulation and rotator joints, tubing, etc. Makes it very difficult to have something tailored and fitted, which seems to be what SpaceX is trying to do. There could be a mobility advantage in having a suit that is closer to your body though, as in less risk of having your suit tangled or damaged by objects around you.
I'm not really making a judgement about their competence, the results just didn't turn out well. I think these things are indeed very difficult. To hazard a guess about the competency behind this, they had some people filling double roles doing the fashion of the suit. That they essentially asked an engineer with a side gig as a designer to make it.
