Answer:
Step-by-step explanation:
An engagement ring is likely very precise. The ring sizes used by some jewelers differs from the next size by 0.8 mm. As a % that's .8 / 16.5 * 100 = 4.80 %
The 0.8 is the number of mm needed to go from a size 6 to a size 7 ring size. So if you are ever going to buy a ring, be sure and let a jeweler measure the finger that it will go on.
The 16.5 mm is the diameter of the ring in mm. for a size 6 ring. If you have different information, you should go with what you have,
Size 14 dress
I can't answer this: it depends on where you live -- Europe or the US.
Also the type of dress matters: is it a skirt or a skirt and blouse combination. The % of the sides is much larger than 4% for the ring but it is still a definite description.
Small Medium or Large
Depends entirely on where the garment is made, and where it is being sold.
Wish tells you to add a size if you live in North America. This too is not very distinct.
