"Short men should not wear cuffs on their trousers."The people who purport this believe they break up one's legs visually. Not sure where this started or why, because it would take more than a bit of folded fabric in the same place as your shoes to do that. Not only is it a nice visual touch on trousers, it anchors down the legs slightly, improving drape on lightweight fabrics such as tropical wool, cotton, and linen. A side benefit with khakis is that, when the bottom of the cuff is worn and frayed, they can be turned inside to look newer and prolong their life in your wardrobe.

Going back to the myth, part of the reason it's untrue is because cuffs (turn-ups in the UK) can be made proportionately smaller or wider according to your physique. The taller man can choose 1.75" or 2" cuffs. (I'd stay away from those fashionable 2.5" Thom Browne cuffs unless you're the rare height of 7' or more.) Shorter men can go with cuffs down to about 1.25". A good median that most clothiers go with by default is 1.5", so try that if you are unsure. If you don't want cuffs, that's fine, though a good tailor can make an inner cuff or add hem tape to help light weight fabrics drape nicer. This leads into my next one, also related to trousers...
"Pleats should always have cuffs, plain fronts should never have cuffs."This one makes my eyes roll every time. It's dull and uncreative. Trousers for black tie are allowed to have pleats yet cannot have cuffs because the latter don't go well with the formality level. That is reasonable. Does that not look fine on all other trousers though? I should point out that the British don't cuff their trousers as much as Americans do, so it's also a rather USA-centric belief. Conversely, I rather like the look of plain front trousers with cuffs. It's something you don't see too often. (Except perhaps on the Ask Andy Trad Forum.)

"Only thin men six feet or taller should wear double breasteds."I've seen too many guys wearing double breasteds that don't fit into this magical body standard and look just fine for this myth to hold true. Some men won't even wear pea coats because they're afraid it's suddenly going to make their 5'10 frame look like Danny DeVito. Gentlemen, this is silly beyond measure. The cut matters more than the style. Double breasted jackets with a smaller wrap or in a 4x2 style will look better on short or rotund men (there's also 4x1, but many sartorially-inclined men eschew this and 6x1 because of their '80s connotations). Admittedly, these are harder to find off the rack but a good MTM or bespoke tailor can make you one. A lot of women's double breasted clothing is designed with fewer buttons or a smaller because it don't visually broaden the torso as much. A slightly shorter than butt length jacket will also flatter the "vertically challenged" by making their legs look longer. This goes for any style jacket, though.

"Bluchers should never be worn with suits, only balmorals."This "rule" seems to have only come about with the rise of the internet iGentry where it is repeated ad nauseum on just about every menswear forum. Yet plenty of men have and continue to wear bluchers with suits and look fine. In fact, none of the great sources of menswear advice (Flusser, Boyer, Gilchrist, etc.) have ever said that bluchers are inappropriate with suits. Period. The typical argument is that they are too casual. I can see how balmorals look more formal, but that shouldn't discount bluchers or the related derby for that matter entirely. Casual looking suits such as those made of linen and cut as three-roll-two sacks especially look at home with them. The latter are often worn with long wings (almost always bluchers) by the "Trad" following. It's all about the level of formality you wish to present. Even at most job interviews, they're not going to take off points because your conservative dress shoes are the wrong style of conservative. It's more important to make sure they're well polished.
