In a world oversaturated with fashion statements, the concepts of semi-formal and formal attire might feel more like vague categories than official protocols. Nevertheless, both semi-formal and formal dress codes entail a set of sartorial\u00a0principles by which every man should abide, lest he wants to show up to his best mate's wedding underdressed...or overdressed for that matter (though overdressed is better than underdressed). Naturally, that doesn't mean the two menswear arenas are one in the same.\r\n\r\nAs you might suspect, the men's formal dress code is elegant in presentation but rigid in scope. By contrast, the men's semi-formal dress code--while still quite sophisticated--gives you a greater opportunity to show off some personal style. Of course, you still might be asking: what exactly\u00a0is the men's semi-formal dress code? And while we're at it: what is the men's formal dress code? Last but not least, what are the differences between the two? Well, seek and ye shall find. In other words, we're breaking it all down below.\r\n\r\n\r\nYou may also like:\r\nSmart Casual Men\u2019s Dress Code Guide\r\nA Guide to Men\u2019s Dress Codes\r\nWhat Style of Dress Shoe Should Every Guy Own?\r\n\r\n\r\n\r\n\r\n\r\nWhat is the Semi-Formal Dress Code?\r\nPreferred by a wide majority of young men, semi-formal attire aims for "smart style", meaning elegant menswear graced with the personal touch. And while some might say the men's semi-formal dress code lands right in the middle between formal and informal attire, the truth is it's much closer to formal menswear in spirit. Think blazers with matching trousers, two-piece suits (with or without the tie), pocket squares and dress watches, and you're heading in the right direction. For night time events, darker colours like navy are the best way to go. However, for daytime events, you can go lighter on colour.\r\n\r\nBecause the semi-formal dress code for men allows for greater flexibility in terms of colour, pattern, material and style, it comes off as a more relaxed version of its formal counterpart. In fact, semi-formal attire, in general, might be best thought of as formal attire, minus the shackles of sartorial obligation. That is to say, that semi-formal attire is still dressy, but you're wearing the suit you want to wear as opposed to the suit you\u00a0have to wear.\r\n\r\n\r\nWhat is Formal Attire?\r\nSynonymous with the black tie or white tie dress code, men's formal attire is for those events where only the most elegant get-up will suffice. In essentially all instances, that get-up is a tuxedo. However, while the strings of style are tightened significantly when it comes to formal dress clothes for men, that isn't to say there's no room for (very slight) improvisation. For instance, a blue tuxedo will always infuse the formal dress code with a touch of the semi-formal spirit.\r\n\r\nUltimately, however, the men's formal dress code takes the word "code" to heart. For the most uber-fancy of occasions, the white tie dress code applies, meaning a white bow tie with a tailed jacket and white shirt. Take that formality down one notch and you're in black tie territory, which typically involves a tailless jacket, a waistcoat and a black bow tie. For daytime events, the strings of formality loosen slightly, allowing for things like a morning coat and striped trousers.\r\n\r\n\r\nThe Ultimate Difference Between Form and Semi-Formal Attire\r\nThe primary difference between the men's semi-formal dress code and men's formal dress code boils down to limitation, or lack thereof. In other words, the semi-formal dress code allows for more personal expression, but still mandates things like a suit or blazer ensemble. Meanwhile, the formal dress code is anchored by the tuxedo, along with some narrowly specific sartorial mainstays, which can vary depending on the event.\r\n\r\n\r\nDos and Don'ts of the Men's Semi-Formal Dress Code\r\n\r\n \tDo\u00a0wear a nice two-piece tailored suit or elegant tailored blazer with matching trousers.\r\n \tDon't\u00a0wear something as fancy as a tuxedo, or something more casual than a blazer.\r\n \tDo\u00a0wear lighter colours and materials during daytime events, and darker colours at night.\r\n \tDon't\u00a0wear bright colours and loud patterns at night time events.\r\n \tDo\u00a0wear a tie if you want to.\r\n \tDon't\u00a0wear a tie if you don't want to.\r\n \tDo\u00a0wear socks along with polished dress shoes of premium leather.\r\n \tDon't\u00a0wear casual shoes.\r\n \tDo\u00a0overdress if you're not entirely sure what to wear.\r\n \tDon't\u00a0underdress if you're not entirely sure what you wear.\r\n \tDo\u00a0accessorise.\r\n \tDon't\u00a0overdo it with accessories.\r\n\r\n\r\nDos and Don'ts of the Men's Formal Dress Code\r\n\r\n \tDo\u00a0wear a tuxedo.

If you're not feeling the two-piece suit, opt for a tailored blazer with matching trousers instead. Be sure to stick with high-quality fabrics and classic colours like navy, beige or grey. In the shirt department, white never fails, but you can also wear different colours or patterns, especially during daytime events. Ties are optional, while socks and dress shoes like Oxfords or monk straps are (more or less) mandatory. Feel free to accessorise with a dress watch or pocket square, but try not to overdo it in the bling department. Just remember, you're not reinventing the wheel, rather smoothing it out to accommodate your personal sensibilities. Pull it all off properly and you'll definitely be rolling up in style.\r\nHave you subscribed to Man of Many?
