Matters needing attention in choosing ring style for 7cm finger

2. Wear a ring with unique design: Women with thick fingers can choose a ring with patterns or diamonds, which can divert people's attention. But don't choose too complicated a design. Simple and exquisite is the best.

3, wear a ring of more than 5mm: If the ring holder is too thin, it will appear thicker, so it is best to choose a ring of more than 5mm, which can make your fingers look slimmer.

4, choose a ring with the same thickness as the knuckles: people with thicker fingers should try to choose a ring with the same width as the knuckles. If it is too tight, it will highlight the size of the knuckles and look awkward.

5. Choose a ring with adjustable size: There are many rings on the market that are not closed and can be adjusted by themselves, which is very suitable for people with thick fingers. Even if the fingers become thinner or thicker in the future, it will not have much impact.
