What’s the most popular bra size to buy online? We asked the experts behind online bra retailer to find out, as the company celebrated selling 5 million bras this week. “We offer bras in 260 different sizes, and our top-selling bra size is 36C,” the site’s founders Noah Wrubel and Bill Richardson told So, how many bras is that exactly? About 260,000 since the site started 13 years ago. “Our best-selling bra size only represents five percent of our total bra sales, which really speaks to the diversity of women’s bra sizes.” And while Wrubel and Richardson noted that the average bra size in America is 36DD, the 36C remains a popular choice—Bare Necessities sell around 200 bras in that size per day.
