Although 'Hose' looks like the English word 'hose' (garden hose), it means 'pants' or 'trousers'. This is a common source of confusion.

I wear an old pair of pants for gardening.
In German, 'die Hose' is usually used in the singular to refer to one garment with two legs. So you say 'eine Hose' (a pair of pants), not 'ein Paar Hosen' (a pair of pants).

I bought myself a new pair of pants yesterday.

to succeed
'in die Hose gehen' and 'gelingen' are clear opposites. The expression 'in die Hose gehen' is colloquial and means that something fails or goes wrong. 'gelingen' means that something succeeds and has a good result. Important: this is not about 'die Hose' as a piece of clothing, but about the fixed expression. If a plan, an exam, or an attempt goes well, you say 'es gelingt'. If it goes badly, you can say colloquially: 'Es geht in die Hose.'
