All I did was ask a simple question. Are they appropriate to wear in a war-like setting (regardless of fantasy)?

Glamour doesn't 'change' what you wear, only the appearance (that's where the "magic" comes in. If we actually wore what we glamoured, we'd be incredibly vulnerable). So while my Roe may look like someone you'd expect to 'wake up' in Pulp Fiction, he's still appropriately geared.
