All this talk about cultural diversity makes me wonder, how indicative of the cultures are the Hempen and Starter gear?
Looking at the lore book, each race has a small section dedicated to how they dress but some of the descriptions are really basic...

Hyurs: Like mixing cotton and leather. Prefer highboots.
Elezen: Sharply cut attire to play off their build.
Lalafells: Scarves and loose-fitting clothes for traveling.
Miqo'te: Little-to-no armor and tail-holes in pants.
Roegadyn: Show off muscles.
Au Ra: Scale belts and tactical tears to look tough.
