Pants = 裤子 [Kùzi]
Someone holds up something that cannot decide what it is: it has a drawstring waist and two legs, but also sleeves with cuffs. Whatever went wrong here, the part with two legs is 裤子.
裤子 (kùzi) means “pants” or “trousers.” The 子 is a neutral tone, short and light, even though the drawing writes it with a tone mark.
Count pants with the measure word 条 (tiáo): 一条裤子 (yì tiáo kùzi), one pair of pants.
这条裤子太长了。 — Zhè tiáo kùzi tài cháng le. — These pants are too long.
我想买一条裤子。 — Wǒ xiǎng mǎi yì tiáo kùzi. — I want to buy a pair of pants.
