The actress - who plays Samantha Jones in the series - told Vogue that her larger frame often meant that her character was dressed in vintage pieces.
"I'm not a sample size like Sarah [Jessica Parker] and Kristin [Davis]. I couldn't wear a lot of the clothes the young designers would send us," she explained.
"I'd wear a lot of vintage... Sometimes the fittings would be eight hours' long and your whole body would ache from having clothes pulled on and off."
However, Cattrall denies feeling slighted by her wardrobe.
"I was never into any of Charlotte's (Davis) sweet dresses or Sarah's outfits," she said.
"There were a few pieces of Sarah's that I liked on their own but not the outfits as such. The thing about [stylist] Patricia [Fields] was that she knew the actresses body types very well."
Cattrall recently admitted that she is unsure if there will be another Sex And The City film.
