Hi, it takes about 5-10 business days to Malaysia.
[Re] Chest size
Thank you for your inquiry. The chest size is measured on flat both sides(rounded)
Just checked a UK 14-16 is 96cm-101cm for chest, I would recommand M size. However, the best way to choose a size is to take out your favorite sweat shirt and measure the chest size on flat so you know exactly what size is the most comfortable one for you^^
