As I received a few questions about ASOS, so sorted them out and maybe the information could be also helpful for you.
光看對服裝材料的描述,我怎麽知道哪種是有彈性(就是穿上後緊緊貼在身上),哪種是少/無彈性(不從上到下靠彈性貼身但是靠裁剪合身)?
It's a big topic.
Basically, almost all ASOS fabrics ( for the clothes) are 是有彈性 unless it is marked as 100% cotton. Most of the design for this brand need 有彈性 fabric because they are very fitting.
I think the more natural portion like cotton, wool or linen ( viscose could be considered as one of them because it's from wood), the better. Because with more natural portion in the fabrics, you can feel very comfortable with the clothing.
My point is: try to choose fabric with more natural portion. Don't need to worry about 有彈性 or not. ASOS has done a very good job on 有彈性.
One more tip, you might have noticed that on the right hand top, there's a small button for currency. You can choose the currency in your region, then all the sizes for clothes will automatically changed to the one you are using in you region. The size I mentioned in my previous posting was UK/AU size. As far as I know, the sizes in different regions are very different.
Once you receive the clothes you bought, always keep the return sheet (with the clothes) for return (within 28 days after you receive the goods) until you are 100% sure you will keep them. If you change idea, you have to return the clothes with the sheet.
When you return any unwanted clothes, make sure to keep all the records from post office. Just in case ASOS doesn't receive your return or have a delay to process your return, you can scan the receipt from post office to let ASOS check for you.
Have fun and good luck!
