这枚短裙别针是我在旅行时买的纪念品，比普通胸针更有故事。

Zhè méi duǎnqún biézhēn shì wǒ zài lǚxíng shí mǎi de jìniànpǐn, bǐ pǔtōng xiōngzhēn gèng yǒu gùshi.

This kilt pin is a souvenir I bought while traveling; it has more of a story than an ordinary brooch.

你先别急着买新的短裙别针，我家里可能还有备用的可以借你。

Nǐ xiān bié jí zhe mǎi xīn de duǎnqún biézhēn, wǒ jiā lǐ kěnéng hái yǒu bèiyòng de kěyǐ jiè nǐ.

Don’t rush to buy a new kilt pin; I might have a spare at home that I can lend you.

他把短裙别针擦亮以后，整套衣服看上去立刻精致了不少。

Tā bǎ duǎnqún biézhēn cāliàng yǐhòu, zhěng tào yīfu kànshàngqù lìkè jīngzhìle bù shǎo.

After he polished the kilt pin, the whole outfit immediately looked much more refined.
