This week's most talked about fashion detail is the so-called belly or waist bag - or the beck bag as it has also come to be called.

This is after Jensen's primary school in Gothenburg has issued a dress code where they recommend students not to use bags or soft pants like this.

But the bag does not have the same status elsewhere.

- In recent years, this bag model has been very trendy.

We have seen that it has been produced by fashion houses such as Gucci, Prada, Versace, Louis Vuitton.

So this is also a bag that has been in the highest layers of international fashion.

If you go even further back in time, it has been associated with different types of youth cultures, "street style", but also in between with the traditional dad look, says Philip Warkander, senior lecturer in fashion science.

A class trip in the world of fashion

The Becknar bag has been on a journey for a long time.

Maybe we can trace the archetype all the way back to the ancient iceman, Ötzi, who was found frozen in the Alps after more than 5000 years - with a small stomach bag.

If we go back to the 1960s and 70s, a similar model has become fashionable among Swiss skiers.

Then under the name "bauchtasche".

Today, the bag has changed shape again and become undesirable, associated with crime, exclusion and macho culture, according to the school in Gothenburg.

- I think this word macho culture is the key to understanding it.

There is a certain type of masculinity that you have problems with.

This bag is used as a symbol to say something about a certain type of guy, a certain type of descent, a certain type of residential address.

That it is these elements that say that they are not desirable in the inner city, says Philip Warkander.

The context sets the meaning

- These meanings that we attribute to the way in which different textiles are combined, depend on what contexts we move in, who we are and who wears them.

In some cases, a garment can be seen as criminal, like a bag in a schoolyard in Gothenburg.

In other cases, on a catwalk in Paris, it can look like the height of fashion, says Philip Warkander.
