There is no English equivalent for the Spanish verb 'estrenar' when referring to a new dress or a new flat. 'Release' is a good equivalent for a film only. Several words are needed in English to convey the idea of 'estrenar (un vestido)' and, even using them all, as a Spanish speaker, I'm always left with a sense of incomplete communication when it comes to saying 'hoy estreno vestido nuevo' in English.

Hi Eli.

Not a bad effort. 'Releasing' is sometimes used in English when talking about new things, but only really when talking about something that has been created and is for sale. So for example you might say 'My favourite band has released a new song' or 'Stephen King is going to release a new book'. 

In your question you say "we are using something new", so in that case you should use a verb that connects to the item you are talking about:

I am living in a new flat.

I am wearing a new dress.

Hope that helps.

Chris

Thanks to all, this is new information for me. I have to live without "estrenar" spanish verb :)

This is interesting!

I think the Italian language has 'sfoggiare', a lady could very well say:

Alla festa sfoggero` il mio nuovo vestito.

Sorry if I was out of line, I wrote just as there are many similarities between Spanish and Italian)

To Chris: when woll the new Stephen King's book be release? I'm looking forward to read it, or maybe to listen to it via an audiobook. Thanks for citing one of my preferred authors, who does not write thrillers, but true epic stories (titanic fights between good and evil).
