HOW THE HOLIDAY CAME TO BE

A retailer built a holiday to sell its product.

Freshpair, an online underwear retailer then based in Fairfield, New Jersey, created the day as a promotion for its own store, and has stated publicly that it was created on August 5, 2003. Its federal trademark applications give a different date for first use of the name, June 1, 2003.

INTRO

Freshpair needed two applications to own a name it invented

National Underwear Day is not a national day in any official sense. It is a phrase an online store spent nearly five years trying to own, and the federal government's first answer was no.

Freshpair applied to register the name in April 2004. An examiner refused it, then issued a final refusal in June 2005. The registration the company did receive, in May 2006, landed on the Supplemental Register, the secondary list the trademark office keeps for marks that are not distinctive.

It came with one more condition. Freshpair had to disclaim the word underwear, the step federal law reserves for an unregistrable component of a mark. The name survived intact, but the claim to its central word did not.

ORIGINS

Underwear Day history

INTRODUCTION

Underwear was one garment before it was two. Cooper Underwear Company built its business on White Cat union suits, and patented a version it sold as the Kenosha Klosed Krotch. By 1912 it was selling faster than the company could produce it, by the company's own account.

CHAPTER 01

Teaching America to shop for underwear

The one-piece did not give way all at once. In 1929 Cooper's cut it down to a short-legged, sleeveless version called the Singleton and sold it in cellophane bags, which the company calls a first in the underwear trade.

The brief itself arrived in a store window. Coopers put its legless design on a mannequin at Marshall Field & Company in Chicago on January 19, 1935, a day Smithsonian Magazine describes as blustery and cold. Six hundred packages were gone by noon.

Three years later the company staged one of the first underwear fashion shows, at a retail convention in Chicago, and called it "The Cellophane Wedding."

CHAPTER 02

A store invents a holiday

Freshpair was an online underwear retailer, founded in 2000. In 2003 it gave itself a holiday, and it has never been consistent about when. Its own announcement says the day "was created on August 5, 2003," while both trademark applications give a first-use date of June 1, 2003.

The second application, filed in July 2008, took a different route. It claimed the phrase had acquired distinctiveness, the statutory path that lets the office accept five years of substantially exclusive and continuous use as evidence that a mark has become distinctive. The claimed first-use date fell just over five years before that filing, and the Principal Register accepted the mark in February 2009.

CHAPTER 03

Times Square, 2013

The eleventh observance was not going to be another fashion show. Freshpair and the radio station Z100 called New Yorkers to Broadway on August 5, 2013 to attempt a world record.

"We'd been in Times Square three times before, but those had been fashion shows with models," company president Matthew Butlein told DNAinfo. "This year, we wanted it to be about everyone."

The judges counted 779 people in their underwear. The record they had come to beat was 2,270.

TIMELINE

Timeline

The brief reaches a store window

Coopers put its new legless design on a mannequin at Marshall Field & Company in Chicago on January 19. Six hundred packages sold by noon.

An early underwear fashion show

Cooper's staged one of the first underwear fashion shows at a Chicago retail convention, billing it as 'The Cellophane Wedding.'

Freshpair claims the name

The online retailer dates its first use of 'National Underwear Day' to June 1 in its federal filings, and says publicly the day was created on August 5.

The name reaches the Principal Register

A second application succeeds on February 24, registering the mark on a claim that the phrase had acquired distinctiveness through use.

The eighth observance moves online

Freshpair skips the street entirely and runs the day on its website, giving away 5,000 pairs of underwear over the first two weeks of August.

The Times Square record attempt

Freshpair and radio station Z100 gather a crowd on Broadway on August 5. Judges count 779 people, well short of the standing record.

WHY THIS DAY MATTERS

Why National Underwear Day Matters

EVIDENCE

The day's best-known numbers cite nothing at all.

The best-known underwear percentages attached to this day, including the claim that 80% of Americans never change the style of underwear they wear, come from a 2010 Freshpair press release that names no study, survey or source for any of them. The release even hedged its own numbers, introducing them as figures that 'may (or may not) surprise you.'

PROPERTY

The trademark outlived the campaign

The original 2006 registration was cancelled in December 2016 after Freshpair failed to file an acceptable declaration under Section 8. The registration that survived was renewed in 2019 and now belongs to Fresh Pair LLC of Weston, Florida.

COMMERCE

The filing says plainly what the day is for

In the registration itself, the day is not described as an awareness campaign or a celebration but as a service: promoting the sale of underwear by promoting public awareness of the need for recognition of the importance of underwear. The 2008 filing added the arranging of promotional events and commercial fashion show exhibitions.

GOOD TO KNOW

Surprising facts about National Underwear Day

The holiday's official website stopped in 2013

nationalunderwearday.com is still live and still advertises the August 5, 2013 event in the present tense, down to the meeting point on Broadway between 46th and 47th Streets.

Umbrellas were allowed. Ponchos were not

That same site published the record's eligibility rules in full, and the wet-weather clause was explicit: if it rained, participants could carry umbrellas but could not wear ponchos.

The record was set to win an argument about Utah

Guinness World Records notes that the Utah Undie Run, the gathering Freshpair failed to outdraw, was organised to challenge the perception that Utah is an 'uptight' state.

Underwear had a Saturday Evening Post illustrator

Cooper hired Joseph C. Leyendecker, an illustrator for The Saturday Evening Post, to draw its 'Man on the Bag' image, which the company calls a classic of American advertising.

A judge threw out the underwear arrests

When eight participants in Improv Everywhere's fifth No Pants Subway Ride were handcuffed in their underwear, a judge dismissed all the charges a month later.

How to Observe National Underwear Day

EDITOR'S PICK

Look up the registration yourself

The trademark file is public and free to read at the patent office's status database. Search serial number 77519990 to see the owner, the claimed dates and the full prosecution history.

TRACE

Trace an underwear statistic before repeating it

Pick any underwear statistic you see on this date and go looking for the study behind it. Check whether the source names one at all, because the best-known figures on this subject do not.

BROWSE

Browse a manufacturer's own archive

Jockey publishes a decade-by-decade company history covering union suits, the first briefs and its early advertising. It is a corporate account, so read it as the company's version of events.

EXPLAIN

Explain why 'national' does not mean official here

Plenty of people assume a national day carries some form of government recognition, and this one carries none. It is a useful example to hand someone, because the name is private property rather than a public designation.

READ

Read how a crowd becomes an official count

Guinness World Records publishes the standing entry for the largest gathering of people in underwear, including its note that participants had to be assembled in a single area under its guidelines. It is a short lesson in how a claim about a crowd gets adjudicated.

Test your knowledge

How well do you know National Underwear Day?

1 / 8

Which trademark register did Freshpair's first successful registration land on in 2006?

Answer

No. It is an unofficial observance with no governmental recognition, so it is a normal working day. A search of the Federal Register for the phrase returns no documents at all, and the only federal record of the name is a private company's trademark registration.
