Generally speaking, clothing which was produced before the 1920s is referred to as antique clothing and clothing from the 1920s to 20 years before the present day is considered vintage. Retro, short for retrospective, or "vintage style" usually refers to clothing that imitates the style of a previous era.
Is a short form for Vintage. It was originally adapted as a search synonym on eBay to give sellers more room in limited character listing titles. When comparing the two searches on eBay, they bring exactly the same search results. While Google seems to recognize it as a short form, the two variations bring back quite different results.
Applying Webster’s definition – a “vintage t-shirt” is a t-shirt that is not new. That leaves a big grey area, but suffice to say they don’t mean one year old. Some say 10, we say at least 15 years old. On Defunkd, a t-shirt must be at least 15 years old to be considered vintage. That’s why we don’t allow any t-shirts to be posted that were manufactured beyond the year 1999.
A true vintage t-shirt can usually be identified by its tag, with most of them now defunct. Typically they were made with a 50/50 blend of polyester and cotton which ensured they were softer. Although there was also a significant amount of 100% cotton blends.
This term refers to a t-shirt that is also at least 15 years old – yet wasn’t licensed. Many of these were sold out of concert parking lots in the 1970s and 80s. They typically featured original artwork with a style that become synonymous with bootlegs. Given they are actually vintage, they are more scarce (far less were manufactured) and had original designs, they can be just as valuable as a rock artists licensed vintage t-shirts.
Deadstock Vintage or NOS (New Old Stocks)
Used to describe tees printed in another era that became excess/unsold inventory and typically ended up in storage. Most times they are in mint condition, however sometimes storage conditions can adversely effect their condition.
Retro tees are t-shirts manufactured in modern times, using original, yet vintage themed artwork for a nostalgic appeal. They’re printed on new t-shirts that many times are manufactured with softer fabric blends.
Reproduction or Reissue T-shirts
These tees are also manufactured in modern times but they use artwork that was created in another era. Some of them are licensed, some of them aren’t. Metallica for example has reissued many of their 1980s designs. To make things a touch more confusing – some of these were reissued over 15 years ago so reproductions eventually become vintage reproductions.
Bootleg or Counterfeit Vintage
These happen when dishonest people set out to create a t-shirt in modern times and pass them off for true vintage. They make their best effort to copy an original and sought after design. They’ll find quantities of old blank tees or unbranded modern day vintage-esque tees. They they’ll typically post them online along side a small quantity of actual vintage t-shirts to dupe consumers into shelling out of them.
