Last year Karlien Burger, 17, paid $220 for a new dress. This year she hoped to get $150 from it to cover the costs of sewing her own dream dress.
Nicole Kruger, 17, paid $320 for her blue beaded gown and said she would sell it for $180. Last year Lena Kemp picked up her green off-the-shoulder number for $200, reduced from $900, and she was still deciding whether to part with it.
The girls, who all have part-time jobs, planned to splash out on spray tans, make-up artists and hair styles because it was their final year.
"Mum pays for the dress and I pay for everything else," Lena said.
Last year they all kept costs down by doing their own hair and make-up and wearing borrowed shoes.
"I couldn't tell the difference between the girls who had paid for their make-up and the girls who had done it themselves," Nicole said.
It cost $10 to register a dress in the sale at the school today, the fee going towards a student trip to Mexico to do humanitarian work.
Botany Downs Secondary School, in East Auckland, held a successful sale last weekend.
