Η αδερφή μου φόρεσε μωβ μπλούζα στο πάρτι και όλοι είπαν ότι της πάει πολύ.

In Greek, possessive phrases usually use the definite article + noun + possessive pronoun:

• η αδερφή μου = my sister
• literally: the sister of me

This is the normal Greek pattern, not something especially emphatic. English usually drops the in this kind of phrase, but Greek keeps it.

A few more examples:

• ο φίλος μου = my friend
• το σπίτι μας = our house

So Η αδερφή μου is exactly the natural way to say my sister.

Short possessive pronouns in Greek normally come after the noun:

• η αδερφή μου = my sister
• το βιβλίο σου = your book
• ο πατέρας της = her father

Putting the pronoun after the noun is the standard pattern. In English, possessives come before the noun (my sister), but in Greek these unstressed forms usually follow it.

φόρεσε is the aorist form of φοράω / φορώ.

Here it means:

• she wore
• or, more literally in many contexts, she put on

In Greek, the aorist often presents the action as a single completed event. In this sentence, it fits the story-like sequence:

• she wore/put on a purple blouse,
• and everyone said it suited her.

So φόρεσε is a natural past narrative form.

Greek can leave the indefinite article out in many cases, especially after verbs like φόρεσε.

So:

• φόρεσε μωβ μπλούζα = she wore a purple blouse

You could also say:

• φόρεσε μια μωβ μπλούζα

That also means she wore a purple blouse, but μια makes the indefiniteness more explicit, a bit like stressing a in English.

Both are possible; the version without μια is very natural.

Normally, Greek adjectives do agree with the noun in gender, number, and case. But μωβ is one of those color words that is commonly indeclinable in modern Greek.

So you can get:

• μωβ μπλούζα
• μωβ παντελόνι
• μωβ παπούτσια

The word μωβ stays the same.

That is completely normal. So yes, adjectives usually agree, but μωβ is a common exception.

μπλούζα is a broad everyday word. Depending on context, it can mean:

• blouse
• shirt
• top
• sometimes even T-shirt

In this sentence, if the translation you were given says blouse, that works well. But the Greek word itself is a bit flexible and does not always match just one English clothing word exactly.

στο is a contraction of:

• σε + το → στο

So:

• στο πάρτι = at the party / to the party depending on context

Here it means at the party.

This contraction is extremely common:

• στο σπίτι = in/at the house, to the house
• στο σχολείο = at/to school

So στο πάρτι is just the normal contracted form.

πάρτι is a borrowed word from English party, and it is very common in everyday Greek.

Modern Greek uses many loanwords, especially for modern life, social events, technology, and popular culture. So a sentence like this using πάρτι sounds completely natural.

Here όλοι means everyone or they all.

Literally, it is the plural form of all:

• όλοι = all / everyone (masculine plural)
• όλες = all (feminine plural)
• όλα = all (neuter plural)

Greek often uses the masculine plural for a mixed group or for people in general, so όλοι είπαν means:

• everyone said
• or they all said

Both are good English translations.

είπαν is the aorist of λέω (to say).

It means:

• they said

Like φόρεσε, it is a completed past action. So the sentence has a nice narrative flow:

• φόρεσε = she wore / put on
• είπαν = they said

Both are standard past forms used for events in a story.

Yes. In this sentence, ότι introduces a content clause:

• είπαν ότι... = they said that...

This ότι means that.

In many everyday contexts, πως can also be used in a similar way:

• είπαν ότι της πάει πολύ
• είπαν πως της πάει πολύ

Both can be natural.

Just do not confuse this ότι (that) with ό,τι (whatever). The meaning is different.

This is one of the most important things in the sentence.

The expression πάει σε κάποιον / της πάει / του πάει means:

• it suits someone
• it looks good on someone

So:

• της πάει = it suits her
• literally something like it goes to her

The pronoun is της, not την, because this expression works with an indirect-object-like structure in Greek.

Compare:

• Της πάει το φόρεμα. = The dress suits her.
• Του πάει το μπλε. = Blue suits him.

So της is exactly what Greek requires with this idiom.

The understood subject is the clothing item she wore, here μωβ μπλούζα.

So the idea is:

• the purple blouse suits her very much / very well

Greek does not need to repeat the noun again in the second clause because it is already clear from context.

A fuller version could be something like:

• είπαν ότι η μωβ μπλούζα της πάει πολύ

But Greek often leaves that subject unspoken when it is obvious.

In this expression, πολύ means a lot / very much, and in natural English the sentence is often translated as:

• it suits her a lot
• more naturally: it suits her very well

Greek often uses πολύ in places where English may prefer very or very well.

So:

• της πάει πολύ = it suits her very well

That is a natural idiomatic translation, even though the Greek word is literally much/a lot.

Yes, that is possible, but της πάει πολύ already sounds natural and complete.

Adding καλά can make the idea more explicit:

• της πάει πολύ καλά = it suits her very well

But in everyday Greek, της πάει πολύ on its own is very common and idiomatic.

Yes, both exist.

• αδερφή is very common in everyday modern Greek
• αδελφή is the more conservative/traditional form

In normal speech and informal writing, αδερφή is extremely common and completely natural. So learners should recognize both.

The sentence as given is very natural:

• Η αδερφή μου φόρεσε μωβ μπλούζα στο πάρτι και όλοι είπαν ότι της πάει πολύ.

Greek word order is more flexible than English word order because case endings and verb forms carry a lot of information. So some parts could move for emphasis.

For example, you might also hear:

• Στο πάρτι η αδερφή μου φόρεσε μωβ μπλούζα...
• Όλοι είπαν ότι της πάει πολύ.

But the original order is neutral and very natural for storytelling.
