Okay so I have gone from a Size 12 to a Size 16 in a matter of 9 months 
MIL gave me a load of clothes last year (a size 16 at the time!), saying she'd never fit in a size 12 again
MIL is now a Size 12! She approached me on Sunday at a family get together and said 'those clothes I gave you, they won't fit you now. Can I have them back please?'
I stupidly said yes... forgetting I have given them to my sister!
What do I do? MIL is quite blunt and won't be impressed...
But I do feel she was unreasonable to ask me for them in front of people
