Тебе очень идёт эта светлая блузка.

Because the verb идти in this expression uses the dative case for the person.

The pattern is:

кому? + идёт / идут + что?

So:

• тебе идёт = it suits you
• мне идёт = it suits me
• ему идёт = it suits him

Here, ты is the nominative form (you as the subject), but in this sentence you are not the grammatical subject. The blouse is the subject, and you are the person it looks good on, so Russian uses тебе.

Yes, идти usually means to go / to be going, but in this expression it has a different idiomatic meaning:

идти кому-то = to suit someone / to look good on someone

So:

• Тебе идёт эта блузка = This blouse suits you
• literally, something like This blouse goes to you, but that is not how we say it in English

This is a very common Russian expression for clothes, colors, hairstyles, and similar things.

Examples:

• Тебе идёт синий цвет. = Blue suits you.
• Тебе идёт короткая стрижка. = Short hair suits you.

Because the subject is эта светлая блузка, which is singular.

The grammatical subject is блузка:

• блузка = singular feminine noun
• therefore the verb is идёт = singular

If the subject were plural, the verb would also be plural:

• Тебе идут эти светлые блузки. = These light blouses suit you.

So the verb agrees with the thing that does the suiting, not with you.

It is nominative singular feminine, because it is the subject of the sentence.

All three words agree:

• эта = feminine singular nominative of этот
• светлая = feminine singular nominative adjective
• блузка = feminine singular nominative noun

So the phrase means this light blouse or more naturally this light-colored blouse.

This is a good example of adjective/demonstrative agreement in Russian.

Here it most naturally means light-colored.

With clothes, светлый often refers to color:

• светлая блузка = a light-colored blouse
• светлые брюки = light-colored trousers

If you wanted to say lightweight, Russian would usually use another word depending on context, such as лёгкий.

So in this sentence, a learner should usually understand светлая as talking about color, not weight.

Очень means very.

So:

• Тебе идёт эта светлая блузка. = This light blouse suits you.
• Тебе очень идёт эта светлая блузка. = This light blouse suits you very well.

It intensifies the statement.

Its position is flexible, but here очень идёт sounds natural and neutral.

Yes. Russian word order is more flexible than English word order.

The neutral version here is:

• Тебе очень идёт эта светлая блузка.

But you could also say:

• Эта светлая блузка тебе очень идёт.
• Очень тебе идёт эта светлая блузка.

The basic meaning stays the same, but the emphasis changes:

• Эта светлая блузка тебе очень идёт puts more focus on the blouse
• Очень тебе идёт... can sound a bit more expressive

For learners, the given sentence is a very natural standard word order.

It is pronounced idYOT, with stress on ё:

• идёт = ee-DYOT

The letter ё always carries stress. In many printed texts, Russian writers replace ё with е, so you may see идет, but it is still pronounced идёт in this expression.

This matters because:

• идёт has a clear stressed ending
• for learners, knowing that this is really ё helps with pronunciation and recognition

Also:

• тебе is stressed on the last syllable: te-BYE

They can both be translated as suits, but they are used differently.

идти кому-то

Usually means to look good on someone, especially in terms of appearance:

• clothes
• colors
• hairstyles
• accessories

Example:

• Тебе идёт эта блузка. = This blouse looks good on you / suits you.

подходить кому-то / к чему-то

Usually means to be suitable, appropriate, or a good match

Examples:

• Эта блузка подходит к юбке. = This blouse goes well with the skirt.
• Этот размер вам подходит. = This size fits/suits you.

So in your sentence, идёт is the better choice because the speaker is talking about how the blouse looks on the person.

No. It is very common with clothes, but it can also be used for other things related to appearance.

For example:

• Тебе идут очки. = Glasses suit you.
• Тебе идёт красный цвет. = Red suits you.
• Тебе идёт эта причёска. = This hairstyle suits you.
• Тебе идёт улыбка. = A smile suits you.

So the pattern is broader than just clothing, but it is especially common for appearance and style.

Because Russian expresses this idea differently from English.

English often says:

• It looks good on you
• It suits you

Russian uses the dative construction directly:

• Тебе идёт эта блузка

No preposition is needed. The idea of on you is built into the expression идти кому-то.

So even though English and Russian express the idea differently, the Russian sentence is complete and natural exactly as it is.

It can easily mean a general opinion.

The present tense идёт here does not necessarily mean only right now at this exact moment. It often expresses a general fact or judgment:

• That blouse suits you
• You look very good in that blouse

So even though the verb is present tense, the meaning is often broader than a literal action happening now.

No, that would not be natural in standard Russian.

With this meaning, the normal construction is simply:

• Тебе очень идёт эта светлая блузка.

You can say на тебе in other contexts, for example to mean on you physically:

• На тебе красивая блузка. = You have a beautiful blouse on.

But with the verb идти meaning to suit, Russian normally uses the dative alone:

• Тебе идёт...

So it is important to learn идти кому-то as a set expression.
