The standard of beauty is undergoing a shift. As social media gives people the opportunity to show themselves off to the world, no longer do women have to rely on “ad men” to tell them who is beautiful and who is not. Instead, women can show off their natural beauty via social media posts that get tens of thousands of likes and celebrate beauty in all its shapes and sizes.

While there is a movement in how people view beauty in American and the world at large, there is data to support that shift. The average woman is changing. In a recent study published in the International Journal of Fashion Design, Technology, and Education, the average woman is no longer a size fourteen. What does that mean? Keep reading to find out!

The study analyzed more than 5,500 women in the United States. Over the last two decades, the data found that women have increased in size on average. At the turn of the millennium, the average waist size for American women was a slim 34.9 inches. Now it has increased by 2.6 inches to 37.5 inches on average. This change has to do with “greater distinctions” that are “found when considering race and ethnicity.”

“We hope that this information can get out and be used by industry and consumers alike. Just knowing where the average is can help a lot of women with their self-image,” said Susan Dunn—one of the study’s lead-experts.

She added, “And we hope that the apparel industry can see the numbers and know that these women aren’t going away, they aren’t going to disappear, and they deserve to have clothing. That the clothing should fit well, both in style and measurements, and be available elsewhere than back corners or solely online is still a controversial topic. Why?”

The study encourages clothing designers to update what they consider to be regular sizes and what they consider to be plus-size clothing. Because the average woman has increased in size in the United States, clothing needs to be updated to mirror that trend. Instead of expecting women to fit into something they simply don’t fit into, clothes need to be updated to match the modern American woman.

Dunn and co-author of the study Deborah Christel serve as faculty members of apparel merchandising, design and textiles at Washington State University. Because they did the research, they proved that the average America woman no longer wears size 2. Instead, the average woman shops for sizes 16 and 18. Fashion industry experts must update their clothing options to mirror the average woman or be left in the dust as the tides of change flood the land.
