If you are looking for a purely aesthetic collar and are willing to measure your neck this unique collar might be a good option for you. It has a unique design that is different from most collars. It has no D or O rings though so it wont work with a leash. But if you just want something to look nice I think this could be a good option.

I really liked this product, it's very interesting looking and the abundant amount of metal gives this collar a hefty weight. Just make sure it will fit you as the upper threshold is about 17.5 inches in circumference.

This collar has unique appearance the leather is woven through a series of metal rectangles making it look like a series of tubes. The metal ends of the rectangles also contrast nicely with the black leather. This design may make it harder to clean however. The collar is overall comfortable although the rough inner lining can irritate when worn over time. Lastly, this is a big collar I had to add holes to make it fit my neck so you won’t be able to use it as an armband unless your arms are huge
