Please, explain みたのは


> 「制服を買ってみたのは はじめてです」

In this sentence what's meaning みたのは? So somebody said me that it's meaning "I
have got a uniform". But I want know whe (and what is meaning) here there is
みたのは？Thanks for your answer!




<テ形> みる means "try (something) and see," and in this sentence の turns the
preceding verbal phrase into a noun describing the action, "the time [I] tried
(doing something)". は marks this whole thing as the topic of the sentence.

It's not quite "I got a uniform," I don't think, but that's the gist of it; I
might say "This is the first time I tried to buy a uniform."
