mensetsu no mae ni shiroi shatsu o kimasu

It is read:

めんせつ の まえ に しろい シャツ を きます

In rōmaji:

mensetsu no mae ni shiroi shatsu o kimasu

A few pronunciation notes:

• を is written wo, but in modern Japanese it is usually pronounced just o.
• 着ます here is きます from the verb 着る (to wear / to put on), not 来ます (to come), even though both can sound like kimasu.

面接 means interview.
前 means before / in front of.
に here marks a time reference.

So 面接の前に means:

before the interview

This is a very common pattern:

noun + の + 前に = before noun

Examples:

• 授業の前に = before class
• 食事の前に = before the meal
• 寝る前に = before sleeping

The particle の connects nouns and often works a bit like of or an apostrophe-s in English.

So:

• 面接 = interview
• 前 = before / front
• 面接の前 = the before of the interview, or more naturally, before the interview

It links 面接 to 前 and makes the phrase sound complete and natural.

In this sentence, に marks the point in time before which or at which something happens.

So:

• 面接の前 = the time before the interview
• 面接の前に = before the interview

With time expressions like this, に is very common.

Compare:

• 3時に行きます = I go at 3 o’clock
• 会議の後に話します = I’ll talk after the meeting
• 面接の前に白いシャツを着ます = I wear a white shirt before the interview

白い is the i-adjective form meaning white.

In Japanese, adjectives that directly modify nouns usually need their normal adjective form:

• 白いシャツ = a white shirt
• 赤い車 = a red car
• 高い山 = a tall/high mountain

白 by itself is a noun-like form meaning white as a concept or color name, but it does not normally directly modify a noun in the same way here.

So 白いシャツ is the correct natural phrase for a white shirt.

シャツ is a loanword, borrowed from a foreign language, so it is written in katakana.

Katakana is commonly used for:

• foreign loanwords
• some onomatopoeia
• emphasis
• scientific names, etc.

So:

• シャツ = shirt
• テレビ = TV
• コンピューター = computer

A native Japanese word for shirt-like clothing might be different, but for the everyday word shirt, シャツ is standard.

を marks the direct object of the verb.

The verb is 着ます = wear / put on.
The thing being worn is 白いシャツ.

So:

• 白いシャツを着ます = wear a white shirt

This is the basic pattern:

object + を + verb

Examples:

• 本を読みます = read a book
• 水を飲みます = drink water
• 靴を履きます = wear shoes
• 白いシャツを着ます = wear a white shirt

Yes—着る / 着ます can mean both to put on and to wear, depending on context.

In English, we often separate:

• put on = the action of dressing
• wear = the state of having it on

Japanese does not always separate those as strictly.

So 白いシャツを着ます can mean:

• I put on a white shirt
• I wear a white shirt

In this sentence, because it is about what one does before an interview, English often translates it naturally as I wear a white shirt before the interview or I put on a white shirt before the interview depending on context.

Japanese often leaves out the subject when it is understood from context.

So even though English usually needs:

I wear a white shirt before the interview

Japanese can simply say:

面接の前に白いシャツを着ます

The subject might be understood as:

• I
• you
• he/she
• we

depending on the situation.

In a learning context, it is often translated as I because that is the most likely implied subject.

The sentence follows typical Japanese word order, where the verb comes at the end.

Breakdown:

• 面接の前に = before the interview
• 白いシャツを = a white shirt
• 着ます = wear / put on

So the structure is roughly:

time expression + object + verb

A very literal English-style order would be:

Before the interview, a white shirt wear

Of course, that sounds unnatural in English, but it shows how Japanese builds the sentence.

着ます is the polite non-past form. It can express:

• a future action
• a habitual action
• a general statement

So here it works well for something like:

• I will wear a white shirt before the interview
• I wear a white shirt before interviews

By contrast, 着ています often describes an ongoing state:

• 白いシャツを着ています = I am wearing a white shirt / I have a white shirt on

So if the speaker means what they choose to wear before the interview, 着ます is natural.
If they are describing what they are already wearing right now, 着ています would be more likely.

No. Normal Japanese is usually written without spaces.

So this sentence would normally appear as:

面接の前に白いシャツを着ます。

Spaces are often added in beginner materials to make the sentence easier to read and to show where words and particles are.

So the spaced version is for learning, but the unspaced version is what you would usually see in real Japanese.
