20 inch men's necklace: how it looks with what you wear
A 20 inch necklace measures about 51 cm. On most men it rests on the collarbone, which makes it the length that shows the most with the least effort. What it looks like day to day depends less on the chain than on the neckline it meets. This page looks at the 20 inch necklace outfit by outfit. For the length itself, and how to check it fits your neck, see our main guide to men's 20 inch chains.
A 20 inch necklace with each neckline
| What you wear | Where the 20" necklace shows | Width that works best |
|---|---|---|
| Crew neck t-shirt | Just above or on the neckline | 3 to 6 mm, so it reads against the fabric |
| V-neck or henley | Fully visible in the opening | 2 to 4 mm, or a pendant |
| Shirt, one or two buttons open | In the collar opening | 2 to 4 mm |
| Buttoned shirt and tie | Hidden under the collar | 1.5 to 3 mm, flat links |
| Knit or hoodie | Over the top, at the neckline | 4 mm and up |
Chains that suit each look
Under a shirt
Flat chains lie close to the skin and do not show through a shirt. The Flat Snake Chain Necklace in 2 or 3 mm and the stainless steel box chain are the most discreet in 20".
Over a t-shirt
Texture helps a chain stand out against cotton. A 3 mm braided rope, a wheat chain or a 4 to 6 mm Cuban link all read clearly at 20". The Figaro Link Chain Necklace in 4 or 5 mm is a good middle ground between dressy and casual.
With a pendant
At 20", a pendant sits just below the collarbone, in the opening of a shirt. Keep it compact. The Hollow Double Cross Pendant Necklace comes ready to wear on a 50 cm (20") box chain, in silver-tone, gold-tone or black. For a larger pendant, a longer chain works better: see our 24 inch necklaces.
Silver-tone, gold-tone or black?
All the necklaces here are made of stainless steel or titanium steel. Silver-tone is the bare polished steel. Gold-tone and black are platings on steel. Silver-tone is the easiest with every color; gold-tone warms up white, cream and navy; black works best with dark clothes.
Care
You can wear them in the shower, at the gym, at the sea or in the pool. Rinse in clean water after the sea or the pool. Perfume, chlorine and friction wear gold-tone and black plating over time. Every necklace has a 1-year warranty against defects, 30-day returns and free shipping over $60.
