FAQ (8)
In casual speech, people often say `like`, but `as` is more correct for a costume. `Like` implies you look similar, while `as` implies you are playing the role.
No. It can mean wearing a silly costume (informal) or a tuxedo (formal). The context tells you which one it is.
The opposite is `dress down`, which means to wear casual clothes, often in a place where people usually dress formally.
Usually, no. `I dressed up` is sufficient. You only use an object if you are dressing someone else, like a child or a doll.
Yes! You can say `I dressed up my dog as a lion.` It's very common on social media.
It's an idiom meaning you have prepared for something (like a date or event) that was cancelled, and now your effort is wasted.
It can function as a participial adjective, as in `You look very dressed up today!`
`Get dolled up` is much more informal and usually refers to women putting on makeup and nice clothes for a night out.
