The fashion house also pointed to "stagnant domestic demand in some European countries" and said the pressure on its margins was "expected to ease" during the year.
The net profit outcome was to €105.3 million. Sales also dipped 0.6 percent to €777.7 million compared to the figure for the same quarter a year earlier, Prada said.
"The trend in the forthcoming quarters will be more stable," the company said, pointing to a 24.7 percent drop in wholesale sales that had been expected while the group's retail sales went up 2.8 percent to €697.8 million.
It said it had a "very good performance" in North and South America and maintained "solid growth" in China, while Hong Kong, Singapore and South Korea showed "softer trends".
In Japan, Prada said its "strong double-digit growth" slowed down sharply in April due to an increase in sales taxes.
Prada has 551 brand boutiques around the world.
Meanwhile, Miuccia Prada was last week named one of the most powerful women in the world.
