The woman, who was accompanied by a male companion, wandered out of the Elkjøp shopping centre in the Skøyen area of Oslo with the substantial item under her long flowing skirt.
A witness alerted the police after spotting the cumbersome couple leaving the shopping centre at around 8pm on Thursday.
The woman was able to carry the widescreen television clasped between her legs and well hidden under her long skirt, to a nearby bus stop. The police however took up the chase and the pair were apprehended as their bus headed out of the city centre.
Oslo police reported that the incident was all in a day's work.
"It is not unusual that thieves put bits and bobs under their skirts or large sweaters," Tor Grøttom at Oslo police said.
