How to choose your size
The first thing to do before choosing your size is to measure your bust circumference and not to base it on the size you usually wear with high street brands.
Knitting patterns take the bust measurement in centimeters as a reference, and this is what you should use as a basis.
It is also important to consider the recommended ease of the pattern depending on the style, and add it to your bust measurement to find the size to knit.
For example, if you have a bust measurement of 90cm, and it recommends 5cm of positive ease, you should make a size 95cm.
You can use the table of final measurements which is often found at the end of the patterns, and which will give you the measurements of the garment in width but also in length (sleeves and body). Don’t hesitate to adapt them to your body shape by lengthening or shortening them as needed.
Be careful, never choose your final size before checking that you have the correct gauge.
