Now... underpants. H&M Cotton-rich short trunks Large were 33in at waist and are now (on the sample I bought today) 30in.
And unlike the chocolate bar which is marked e.g. "25g", the shorts' packaging lacks any figure to reveal the reduction in the number of inches you are getting.
What next? 11-inch rulers? :)
Speaking of short feet; do you remember? Subway tried peddling "foot-long" sandwiches less than 12 inches. They were hit by a class action suit which they settled back in 2015.
