An invitation to the wedding will be winging its way to you very soon.

婚礼请柬很快就会到手。

We had three invitations to parties.

我们有三张参加聚会的请柬。

She wangled an invitation.

她设法弄到了一张请柬。

I fear being the only one to heed the no-gift clause on the invite and looking like an empty-handed shmuck.

但我担心我是唯一一个意到请柬上“不带礼物”这句话的人，不想到时候看上去像一个两手空空的傻瓜。
