Ready-Tied Bow Ties In Contrast With Freestyle Bow Ties

Self-Tied
Self-tied bow ties are often the more conventional and marginally more standard type of bow tie. Self-tied neckties are lengthy pieces of cloth that have been knotted manually (rather than knotted by a machine). Fashionably prone individuals frequently consider freestyle bow ties as more professional than machine-tied bow ties.
If you are donning one simply because you want to be affiliated with mental ability and/or individuality, I'd generally recommend a freestyle because knots done by hand are typically significantly more personalized when compared to a machine-tied bow tie. Visually, a hand-tied knot will typically come out grander and more voluminous when compared to a pre-tied. Hand-tied knots are in most cases considerably less precise, but depending on your style, the imprecision may add to the allure.
A setback--or prospect, based how you look at it--is that donning a freestyle bow tie commonly requires you to find out how to knot it. Fortunately, if you've got the physical dexterity and thinking ability necessary to understand how to tie a normal tie, you can obviously learn the simplest way to tie a bow tie with only several minutes of practice.
Pre-Tied
Machine-tied ties may be more suitable in cases where you find yourself strapped for free time. For example, any time you're buying neckties for little boys (in most cases for a wedding), I would absolutely suggest pre-tied knots to keep your ceremony as relaxed as possible.
A further condition in which pre-tied knots may be more suitable would be if you were a time-strapped professional. In particular, medical professionals, orthodontists and pediatricians might choose bow ties since they're not as likely to spread microbes than regular-length neckwear and are definitely more difficult for infants to grab. If you're an employee in a situation like this, almost no one is going to fault you for choosing to save 2 to 3 seconds each day for your professional duties.
Similarities
When compared with standard-length neckties, both freestyle and machine-tied bow ties will certainly bring curiosity. If you appreciate being the target of consideration, that could possibly be desirable. Some naysayers consider bow ties odd and wouldn't normally put them on except in formal situations where they are regular. In my opinion, I wouldn't suggest wearing a bow tie for a interview, but a confident man could easily use a bow tie in a relaxed setting if he happened to be so willing. For example, either a freestyle or a pre-tied bow tie could be suitable for a pleasant lunch time out with your family and friends or sweetheart. (Just don't wear a purely black bow tie unless you're the waiter).
