As for fabrics we now have fastskin and tan thru (one on sale in forum) just
to mention two - and the new technology for printing on stretch material has of course produced a revolution in pattern and art representations.

As for design , one never seen now is the lace-up at both hips (perhaps from the sixties).
A sexy bikini, mostly pioneered by the French, was joined at the sides by rings, or fixed with interlocking clips. Looked good on the right body but
would need to be searched out from a specialist supplier these days.

As for better or worse, well there are only so many changes possible in a small garment and many have appeared over the years. Today the Brazilian sunga seems to predominate (instead of the trendy tanga of a few years back) but others may disagree.
