More and more men are wearing ankle-free. What is a no-go in winter can look really casual in summer with trainers and slip-ons. But: high-water trousers require an appropriate cut and are not for formal occasions. "The trouser leg should end approximately at the heel edge of the shoe, espacially narrow-cut trousers end a little bit above that," explains LLOYD expert Björn Wischnewski.

"In leisure time and during sports, short socks are absolutely fine," says the LLOYD expert. "For suit wearers, however, knee socks are the best choice, or at least socks that are so long that no hairy calves protrude from the upturned trouser leg while sitting."

Alternatively, one also says: "No brown after six" – this old British (and, admittedly, somewhat elitist) fashion wisdom says that brown shoes do not have any place in business and at evening events. "Apart from formal occasions, however, this rule is considered outdated today," says style expert Björn Wischnewski.

What seems cool for women quickly looks like carnical for men. Therefore, the following applies: use patterns in a nuanced an discreet way; combine stripes, dots or checks with single-coloured garments. For suits, the following applies: pinstripes always work with Paisley or Gingham (Vichy check), Glencheck only with Gingham.

Fashion rule number one: the last button always remains open – no matter whether it´s a jacket or a cardigan. If it is closed, the silhouette looks disadvantageous and the look stiff.

And if so, with the arm stretched or bent? The formula: with a correct look and the arm hanging down, the cuff edges should come out one to two centimetres from the jacket sleeve and just barely cover the protruding wrist bone.

T-Shirts are a no-go, undershirts only if you don´t see them. Therefore, it is best to wear nothing at all under bright and translucents shirts.

If you are a lifeguard, a postman or a busdriver. And of course at the lake, at the beach bar, in the beer garden. Preferably not in the office, on business trips, at meetings.

A watch. And – if you have one – the wedding ring. Since the watch is often the only piece of jewellery, you should choose it wisely.

That depends on the occasion. What is allowed in your freetime quickly looks unprofessional at work. In general, the following applies: If you wear a jacket, the shirt belongs inside your trousers. If your look is more casual, you can also wear it outside your jeans or casual trousers. Important: shirts that are worn loose should be four to six centimetres shorter than shirts that are tucked into the trousers.

You can´t go wrong with a well-cut and well-fitting suit an discreet colours. Make sure that the festive opera outfit is a different as possible from you normal business look. A fine tie and a white shirt will emphasize the festive occasion, if you like, wear a cufflinks. In combination with: elegant shoes, preferably in black.

"Of course, during sports, in leisure time, on vacation. Whether with trainers, slip-ons or boat shoes, it´s up to your personal taste and style," says Björn Wischnewski. "Only in the office are shorts a no-go for style-conscious men."

Braces give the outfit a personal touch and – just like the belt – ensure that the trousers do not slip. If in the past they had to be worn hidden under a sweater or jacket according to etiquette, today they are considered a fashion accessory and therefore may well be visible. “There is only one thing you need to keep in mind,” adds LLOYD expert Sin Men Ann: “Never wear belts and braces together!”
