Snaps Vs. Zippers Vs. Frog Knots

Traditionally Chinese Girl's QiPao Dresses and Vietnamese Girl's Ao Dai's Dressess used knots, usually frog knots. In ones you buy, I have seen some with knots, snaps, and of course the traditional Frog Knots. I like the zippers, they make it so much easier to take on and off. Snaps, I feel they ruin the look a little of the dress. Frog Knots look nice, but they are challenging to put on.
