look past 表示“不关注”“不注意”“忽视”。

Customers today look past the fact that something is secondhand and focus instead on the fact that they have something unique to wear and are not overstuffing their own wardrobes(衣柜) or contributing to landfill.

句意：如今的顾客不再在意东西是不是二手货，而是关注自己穿的衣服是否有个性——他们不会把自己的衣柜塞得满满的，也不会给垃圾填埋场添乱。

附注：look past 的基本义为“目光扫过”，可引申指“跳过”“不关注”“无视”“不注意”“不在意”等。如：

He looked past me with no sign of recognition. 他的目光从我脸上扫过，好像完全没有认出我。（朗文）

He looked past me to the next customer. 他跳过我去招待下一位顾客。(韦氏）

Burke's article was a cheap shot (= unkind criticism) at teenagers that did nothing to look past stereotypes. 伯克的文章是对无视传统观念的青少年的无情抨击。（朗文）
