The problem is that the Superdry sizes look "different" from other brands on the market (I've put it in reverse arrows). This and the Internet have misleading information on this topic. I decided to settle this once and for all. Or at least as long as Superdry does not change it again. The Superdry is actually very accurate. I know I did not expect you to hear that, so I can explain why.
Clothing sizes have an international standard. The International Organization for Standardization, also known as ISO. They are the governing bodies of all kinds of standards, including the usual gauges for dressing scales. This can in theory be a reference to accurately select clothes and convert the United States, UK, European and other sizes. But that is not the case. There are problems with international standards.
Too deep into these standards, this is beyond the boundaries of this article, so I want to cut off the persecution. The problem consists of two parts; It uses fonts such as Small, Medium, Large and Extra Large, as well as clothing makers who are free to meet established standards. They are not required to comply with the standard, so there will probably be no change in the future. If you look like other clothing brands, it's a good rule of thumb that the Superdry dress is smaller than about one size. They look decent size, but most clothing manufacturers are getting bigger in size, it's better to go bigger in Superdry suits. For example, if you are usually a medium, you buy a lot of Superdry.
Superdry Suit meets international standards; the problem is that other clothing companies do not. Superdry also uses letter codes, so you need to look for a table to convert your size from Small to Chest Size or to the size of a ladies' suit. If you checked your website, you would have noticed that there is no such useful table anywhere.
Men's Superdry Clothing Size Chart
Dimensions in Chest Size in Inches
Extra Small = 36 "
Small = 38 "
Medium = 40 "
Large = 42 "
Extra Large = 44 "
Extra Extra Large = 46 "
The men's waist sizes are very straight forward, just inches, the standard tool, so you should not have any problems with your size
Women's Superdry Scale
US clothing sizes meet ISO standards and do not necessarily match the size that would normally be bought in other clothing brands. It is designed to go with actual measurements (inches)
Extra Small = UK Size 8 / US Size 4 = bust 34 ", waist 25,5", hip 36,5 "
Small = UK size 10 / US size 6 = bra 34 ", waist 26,5", hip 37,5 "
Medium = UK size 12 / US size 8 = bust 35 ", waist 27,5", hip 38,5 "
Expected to be the best advice I can give you before you buy it, but what if you are? there is no shop near you, this is the only chance you can buy online where you can not try the item before you buy it, but there are exceptions like Nucleus. back to your online orders, so you can try out the stuff and send it if it does not fit. This is a small problem for the post office, but at least it will not cost you anything.
