Ordered some clothes for DH's GM, who is in her 90's and slim, but does not like to feel waistbands etc. so DH's Mum (GM lives with DH's parents) asked me to order her size 14 in everything (nightwear, elasticated trousers, cardigans). Anyway, they arrive and DMIL calls me to say can I reorder it all again in a size 10, as what has arrived in size 14, comfortably fits DMIL, who is definitely an 18 in M&S and has 'got a bit spare from Christmas' (her words not mine, and haven't we all!) GMIL usually takes a 14 in other shops and previously in M&S and is not overly skinny, but slim, with an 'overhang' from abdo surgery in her 30's.
AIBU to think that this is ridiculous?
