NANDEEBIE resident Irene Wade was tickled pink when she received a pink frilly g-string for her 100th birthday this month.
Mrs Wade, who moved to the aged care facility in Winchester Road, Alexandra Hills, a year ago, laughed when she received the lacy knickers but didn't elaborate on the secret to her longevity.
Although she didn't put them on during the party, Mrs Wade did twirl the pretty briefs around her finger while guests sang Happy Birthday.
The underwear was just one of many pink presents Mrs Wade received when she threw a Pretty in Pink party to mark the occasion.
Pink scarves, pink teacups, a pink watch, pink balloons and pink roses made the party perfect for the avid Barbara Cartland fan, who was born in Wellington, New Zealand, on May 16, 1912.
Nandeebie chef Karen Gray worked with the pink theme and baked a pink cake in the shape of a butterfly, which was served with pink punch to the 20 guests who all wore pink.
Daughter Beverley Brecknell, who lives at Raby Bay and painted her mum's fingernails a dark pink for the occasion, said her mother was surprised at all the fuss.
"Especially when the city's new mayor, Karen Williams, and Member for Bowman Andrew Laming arrived to wish her well," Mrs Brecknell said.
"It was a happy but hilarious day particularly when she held up the g-string that one of the carers had given her.
"Mum's bridesmaid's daughter also gave a very funny speech about how Irene always wore a g-string, which had everybody laughing."
Mrs Wade, who said she didn't consider herself old, grew up in New Zealand where she met husband Harry, a salesman, who died in 1998.
The couple have two daughters, who both attended the party, along with guests from Western Australia, New Zealand, Sydney and Canberra.
A letter from Queen Elizabeth II congratulating Mrs Wade on her birthday, takes pride of place in her room, along with birthday letters from Governor-General Quentin Bryce, Prime Minister Julia Gillard and Mr Laming.
