At present, the commonly used clothing models are S (small), M (medium), L (large) and XL (large). Ordinary brands don't have the size of 4xl. Generally speaking, L is a large size dress, XL is an oversized dress, and four X's represent a fourfold increase. Only some street brands and fat brands in Europe and America have clothes of this size. As far as China is concerned, such people are rare.

Generally speaking, clothes of size 4xl are suitable for people who weigh more than 180 kg, but there is no special regulation, because there will be inaccurate sizes, which has a certain relationship with height.

You might as well buy clothes of this size and try them on yourself. It is best to produce according to the order.
