Clothing GuideThe key to winter dressing is
layering. Typically you will have 3-4 layers, which consists of:
A) Base layer or thermal underwear
This is the layer next to your skin. The top can be short sleeve or long sleeve (warmer).
Material can be synthetic (e.g. polyester, polypropylene) or natural like wool. There may be also different thicknesses depending on brand or manufacturer (e.g. some classify as lightweight, midweight, heavyweight).
B) Mid layer
The next layer can be a shirt or jumper/sweater, depending on the look you want. If you are going for business meeting then obviously it would be a shirt. Otherwise for just going out, can be jumper/sweater. Or you can add a vest on top of your shirt:

Again, material can be synthetic or natural and different thicknesses are available. For casual wear I find fleece tops to be comfortable and warm.
C) Outer layer
This is your main insulation layer. If you want the best, go for a down jacket:

This is a jacket filled with combination of feathers and down, so it will be puffy and traps heat. When you buy, check the label to see what is the percentage of feather vs down, e.g. 50% feather / 50% down. The more down the warmer (since down is higher grade), but also more expensive. In overseas they use a more accurate rating called fill power, e.g. 500 fill power is average quality, 600+ is better, 700+ is premium and 800+ is super premium - but jackets sold locally rarely use fill power rating. If you want cheaper then go for synthetic fill instead of down. It won't be as warm, but can still work for you.
If it's not bitterly cold, can also use a fleece jacket:

Note fleece is usually not windproof, unless you get the type with a wind resistant layer.
Of course a down jacket isn't formal enough for business meetings. So for meetings you might want to choose a coat:

For winter you'll need a heavier coat, normally made of wool. However, these can be expensive also.
D) AccessoriesDon't forget things like wearing a scarf, gloves and beanie/hat to also keep you warm.
Hope this gives some basic ideas to people about winter dressing. Obviously there are many different types and combinations for you to mix and match.
