Every time I see the skant, two things come to mind:

• Lotta leg-shaving going on. That or leggings. I'm not opposed to either as an aesthetic choice, but it kind adds a layer to the impracticality.
• I think the absence of a belt is what keeps these from reading like a kilt or tunic. Either of which would be a fantastic nod to traditional affectation for earthling personnel (as other races do). Instead, the skant sits in this men's apparel uncanny-valley of sorts, where it's neither a dress, dress uniform, gown, or nightshirt.
