Clearly you aren't thinking belt - one buckle to loosen - tighten. Side adjusters two (2) to tighten - loosen. Scientific studies have shown that the belt would have saved you about 6 months of precious time over the last 5 years if you had the quicker belt option instead of the slow clumsy side tabs. ( thats assuming you work 5 days a week - if its a rostered day off - does anyone still have those? - every fortnight then its closer to 5 months)
Also, I think Benny Hill started the "tie same fabric as your shirt" look. Now people do that and aren't even trying to be funny.
