Malachite, good on you to to feel the sense of completing the male fashion presentation wearing a tie. Devlyn providing a site that show various ways to tie knots should help. Cindy's idea of a bow tie has a classy touch if dressing for a formal night out wearing a jacket. I never learned to tie a bow tie, when I was young I had an elastic or clip on tie. The only knot I ever learned is the Windsor, once you got it down pat you won't forget. With clip on & elastic ties, if you get tired of having that top button around your neck on the shirt done up, you undo the button & then the clip on may not stay on & the elastic will show with a funny gap, so you have to take them off and lose the dress effect. With a knotted tie, undo the top button, you can & may want to loosen the tie a bit you haven't lost the dressy effect.
Lots of good comments by others here.
