IU receives attention for a picture from two years ago

U has recently received considerable success on music charts as well as music shows. However, her current promotions are not all that are receiving attention. Pictures of IU from two years ago have been heating up the Internet. Recently uploaded on an online community under the header “IU’s legendary hot pants”, the pictures received an explosive number of hits.
In the pictures, a visibly younger IU can be seen performing “You Know” in front of an audience. The pictures have attracted a lot of attention because the shorts she has on are extremely short, inappropriate for a girl of 17 years.
Netizens who saw the pictures commented, “Did she have a coordi back then?”, “Those are not hot pants, but panties,” “In the future, don’t wear that kind of clothes,” and “Let’s protect IU.”
The pictures are available below. What are your thoughts on her short shorts?
