Choose good quality items from reputable brands to make the most out of your key items. Even one smart addition to a wardrobe can make a big difference so you don't necessarily need to spend lots of money.
One of the easiest and most obvious ways of tackling the unexpected elements is by always carrying a hat, scarf and gloves with you during the autumn to spring period. If you don't take a bag or briefcase to work, gloves and a hat are compact enough to fit into coat pockets if not needed, and a scarf can be thrown around your neck loosely. For your head and hands, opt for modern thermal materials that are designed to breathe and deal well with nature's surprises. For scarves the most important factor is that they provide protection from the wind, so whether it's made from a "smart" fabric or traditional one worn in a few layers doesn't matter so much.
Choose sturdy footwear in a natural material that's designed to let your feet breathe. Plimsolls and trainers may be incredibly comfortable but they don't give you much protection from the cold, let alone rain. Invest in a quality pair of leather boots or shoes with a proper lining.
Remember to always wear cotton socks for that added layer of warmth, and to make your shoes a more comfortable fit. Leather shoes have a tendency of causing blisters if not worn with socks as the material is quite hard against your skin.
Khaki trousers or chinos are a great choice for showing the weather your strength. After all, khakis are good enough for the army. The fibres used to make the fabrics are predominantly natural so the fabrics provide good protection in cases of temperature fluctuation. Surprisingly, jeans aren't the best idea as the material doesn't do much to protect you from the cold, particularly if wet.
Jackets made from synthetic materials are excellent wind and rain deterrents but aren't the most visually flattering additions to a wardrobe. Many are originally designed for outdoor activities such as hiking and running. Some classic British companies like Barbour, however, provide stylish and fully functional alternatives to what's on offer at most sportswear shops.
For a smart and business-appropriate look consider leather. The material's natural qualities mean it will keep you warm when the temperature drops, but will let your skin breathe in warmer conditions. Seek mens leather jackets online for a bigger selection than what's available on the high street.
