Mine is my Mothercare drawstring waist black maternity joggers, £12 new and worn virtually every day, pregnant or not, for 6 years! And my Uggs. Everyday for 3 winters and now as slippers.
And my Next Boyfriend jeans, worn every time for at-home-with kids days. Far better value than my expensive J Brand going-out jeans...since I never go out!
Just trying to work out what it is worth spending money on.. "lounge"wear and comfy jeans I think?
