Morphology
The sense 'to lose all or most of your money' is idiomatic and cannot be derived from the literal meanings of 'lose' and 'shirt' — a B1 learner who knows the constituent words would likely interpret it as losing an item of clothing. The possessive 'one's' and the clothing noun do not transparently signal financial loss, so prior exposure or cultural knowledge is required to understand the idiomatic meaning.
Etymology
The idiom lose one's shirt may come from old gambling stories where someone lost so much money they had to give up their clothes, even their shirt. So, saying lose one's shirt means 'to lose all or most of your money'.
