OK Jules, time that your mum and your sister both received a piece of your mind. Wear the dress again - infact, wear it every time you go around there. I'm sure it looks lovely and if they say anything say "well, my colleagues think it looks good and I trust their opinion WAY more than yours."

Honestly, the way they're both carrying on is bang out of order.

I can't believe your mum is buying into the whole thing.

Tell them both to go and get lives. They obviously haven't got enough to do.
