美国纽约内衣日NationalUnderWearDay是美国环境健康节日之一，美国全国内衣日期始于2003年，目的是通过展示多内衣，倡导健康生活，提高人们对内衣的重视。

　　每年的8月5日，纽约内衣日热闹起来，纽约市民和游客聚集在时报广场，令人震惊。这次，虽然没有打破只穿内衣聚集在一起的吉尼斯世界记录，但绝对是令人震惊的内衣PARTY。组织者说明年再来，2011年犹他州有2，270人穿内衣跑步记录。

　　In an effort to publicly shine light on “unmentionables,” Freshpair founded National Underwear Day on August 5th, 2003. Over the last 10 years we’ve celebrated underwear by hosting New York City model events, massive underwear giveaways, a pop-up shop in Columbus Circle, and a Times Square runway show.

　　Throughout the years, thousands of people have written us and shared acts of confidence. We’ve heard from cancer survivors struggling to regain their lives, men and women suffering with poor body image, and young and old embracing their sexuality. This year National Underwear Day is about YOU.

　　As the founder of National Underwear Day, Freshpair understands that confidence is the byproduct of believing in one’s self. And this year we want more people to do just that. That's why we're inviting everyone who has ever doubted themselves to join us in attempting to break a Guinness World Record in Times Square. All you need to bring is your underwear.
