kilt height+tie length+button height+heaviness

[Thekiltedmohawk]

The trick I use on my ties by shorten the long end before knot it. So, the smaller end will be longer than the bigger end. The vest itself will cover the funny-looking tie, and I don't have to worry about tucking in long end in above my kilt. The "longer" small end ended up just above my belly button. My profile picture is the example of that as well.
