In an email, the buyer wrote that Smith's listing was "brilliant" and that he just wanted to "support it".
He even suggested Smith frame the dress (which he was also happy to pay for) along with her photo with television news presenter Hilary Barry, who came down especially to join in the hilarity of the failed internet purchase.
Smith spent an afternoon with Barry searching the shops of Napier and successfully finding another dress.
Enthusiasm and support saw the dress reach up to $180 by Friday afternoon.
Smith was in disbelief.
"It only cost me $27, they could just go on to Ali Express and get themselves one, I'm just amazed."
Despite the rip-off purchase, it hasn't hindered the fashion lover from buying more quirky dresses via the internet.
"I'll still order from Ali Express, but I'll just make sure that I go up four sizes at least before making the purchase, I wouldn't trust the size chart at all."
While many have experienced an online shopping fail, Smith said many women had reached out to her. "I've had a lot of people saying thanks for sticking up for us bigger girls. I'm a size 18-20 and a lot of people keep saying 'thank you for being brave', I don't think I'm being brave, I think the whole thing's hilarious."
