The problem is that Superdry sizes 'appear to be different' from other brands in the market (I've put that in inverted commas for a reason). That and the internet is plagued of misleading information on this topic. I've decided to sort this out once and for all. Or at least until Superdry change things up again. Superdry is actually very accurately sized. I know you were not expecting to hear that so I will explain why.
The Problem with Standards
There is an international standard for clothing sizes. The International Standards Organization, also known as ISO. They are the governing body for all sorts of standards, including a standard measure for the sizing of clothes. This should, in theory, give us a reference to be able to accurately choose clothes and convert between US, UK, European and other sizes. But it does not. There are problems with the international standards.
Getting too deep into these standards is beyond the scope of this article so I'm going to cut to the chase. There problem comes in two parts; Using letter codes like Small, Medium, Large and Extra Large and clothing manufacturers taking liberties with the established standards. They are not obliged to conform to the standard so there is not likely to be any change in the future. When compared to other clothing brands, a good rule of thumb is that Superdry clothing is approximately one size smaller. They are sized to fit properly but as most other clothing manufacturers are getting more and more generous with their sizing, it's better to go for one size bigger in Superdry clothes. For example, if you are usually a medium then you buy a large in Superdry.
Superdry Size Chart
Superdry clothing complies with the international standards; the problem is that other clothing companies do not. Superdry also use letter codes, so there must be a look up table to convert a size from Small, to chest size or women's dress size. If you've looked at their website you would have noticed that there is not such a helpful table anywhere to be found. I've developed a Superdry size chart.
Men's Superdry Clothing Size Chart
Sizes are chest sizes, measured in inches.
Extra Small = 36 "
Small = 38 "
Medium = 40 "
Large = 42 "
Extra Large = 44 "
Extra Extra Large = 46 "
Men's waist sizes are pretty straight forward. They are all in inches, the standard measure so you should not have any problems selecting your size.
Women's Superdry Size Chart
The UK and US dress sizes are matched to the ISO standards and may not necessarily match up to the size you would normally buy in other clothing brands. It is intended that you go by the actual measurements (in inches).
Extra Small = UK Size 8 / US Size 4 = Bust 34 ", Waist 25.5", Hip 36.5 "
Small = UK Size 10 / US Size 6 = Bust 34 ", Waist 26.5", Hip 37.5 "
Medium = UK Size 12 / US Size 8 = Bust 35 ", Waist 27.5", Hip 38.5 "
Large = UK Size 14 / US Size 10 = Bust 36 ", Waist 28.5", Hip 39.5 "
Buying Superdry Clothing
Probably the best advice I can give you is try before you buy but what if you do not have a store near you? Is this case you are left with the only option, to shop online where you can not try the item on before you buy it. There are exceptions however. Some stores, like Nucleus, offer free return postage on internet orders so in effect you can try the stuff on and send it back if it does not fit. It's a slight hassle getting to the post office but at least it will not cost you anything.
