You will see many men in Fiji wearing sulas ( skirts below the knees). Most Indian women cover up in long saris. Fijian womem usually wear long dresses or skirts. This is a big difference than back when the men just wore a loin cloth and the women wore grass skirts.
Fiji and its waters
My stay in Nadi was actually fairly brief, maybe about 8 hours. However, my overall stay in Fiji islands was over 12 days. From Nadi, a few of my friends and I packed into a small 6-seater plane and hopped to a smaller island were we quickly got on board a boat for a liveaboard dive trip.
The islands can be mountainous and are lush with tropical plant life. Since the islands are relatively small, the terrain might be steep, but does not reach extreme elevations.
The diving is great. Being a volcanic archipelago in the deep open ocean, it has some shallows around the atolls and some really deep spots too.
If you have planned your stay, or will be planning your stay to be a liveaboard diving trip, try to see if your boat has any agreements with the local islands. If you are privileged enough, your boat might have permissions to beach on the local islands were other civilians are not allowed. You can walk among the small villages. The school kids will rush to your side eager to meet and greet you and be your tour guide for some pocket change. You could even be invited in to see a local dance and sip some cava.
