Ordered 6 tops from H&M as needed new clothes for work. Am generous of nork so ordered all 18s. Half are so big they are falling off me the other half are way too small. They don't tend to do bigger sizes in store so I need to order online but now have to send them all back. Another vote for standardised sizing across stores here too! They should give them random numbers or something to avoid the whole vanity sizing thing.
