A few years ago on a trip to England I bought some shirts in the Sainsbury's "Tu" range - in a size 18 & 20. Told myself their sizes must be on the skimpy side! Now, having nearly reached target, I visited Sainsbury's again and bought some jeans - same "Tu" range - this time a size 8. Whoopee! Now I'm telling myself their sizes must be on the generous side! I'm confused!
