As the trainer is highly elasticated, the measurements of the trainer can be misleading. We recommend buying according to your UK clothing top size. The Everyday Trainer is highly elasticated so can fit half size up or down. That does not mean you should buy a size down as it may overstretch and break if you do, so please buy your recommended size according to your UK Top Size (measurements shown below in table).
E.g. If you are an UK size 8 in tops or around the waist, go for the size 8/10 if you are a bigger size 8, or a 6/8 if you are a smaller size 8.
