Η φίλη μου φόρεσε μπεζ παπούτσια με το καινούριο φόρεμά της.

Η φίλη μου literally means the friend of me, but in natural English it is my friend.

Greek very often uses:

• article + noun + possessive pronoun

So:

• η φίλη μου = my (female) friend
• ο φίλος μου = my (male) friend / my boyfriend depending on context

Here φίλη is feminine, so it specifically refers to a female friend.

In Greek, possessives like μου, σου, του, της are commonly used together with the definite article.

So Greek says:

• η φίλη μου
• το σπίτι μου
• ο αδερφός της

This is normal Greek structure. You should not translate it word-for-word into English. Even though Greek includes the, the whole phrase simply means:

• my friend
• my house
• her brother

Greek possessive weak pronouns usually come after the noun:

• η φίλη μου = my friend
• το βιβλίο μου = my book
• η μητέρα της = her mother

This is one of the most common patterns in Greek.
Putting μου before the noun is generally not the normal structure in a simple sentence like this.

Φόρεσε is the aorist form of φοράω / φορώ.

Here it means something like:

• she put on
• she wore

The Greek aorist presents the action as a complete event. In this sentence, it refers to one finished action in the past.

Compare:

• φόρεσε = she put on / wore
• φορούσε = she was wearing / used to wear

So φόρεσε sounds like a single completed act: she wore/put on those shoes.

It can suggest either, depending on context.

With clothes, φοράω in Greek covers both ideas more broadly than English sometimes does. In this sentence, English might translate it as:

• My friend wore beige shoes with her new dress or
• My friend put on beige shoes with her new dress

If the meaning already shown to the learner is wore, that is perfectly natural here.

Normally, Greek adjectives do change to match the noun in gender, number, and case. But μπεζ is a borrowed color word and is usually indeclinable, meaning it does not change form.

So you get:

• μπεζ παπούτσια
• μπεζ φόρεμα
• μπεζ τσάντα

The form μπεζ stays the same.

Παπούτσια is the neuter plural form of παπούτσι = shoe.

So:

• το παπούτσι = the shoe
• τα παπούτσια = the shoes

In the sentence, μπεζ παπούτσια means beige shoes.

Because it is plural, English uses shoes, but Greek uses a normal plural noun, not a special pair-construction.

Greek does not always need an article before an object noun. Here μπεζ παπούτσια is an indefinite object, so it means:

• beige shoes not
• the beige shoes

If Greek wanted to say the beige shoes, it would be:

• τα μπεζ παπούτσια

So the lack of article here gives the indefinite sense.

Με means with.

In this sentence, it connects the shoes with the dress:

• μπεζ παπούτσια με το καινούριο φόρεμά της = beige shoes with her new dress

This means the shoes were worn together with the dress, as part of the same outfit.

It does not mean she used the dress as a tool or instrument. It is the everyday with of combination or accompaniment.

Greek often uses the definite article in noun phrases where English may or may not use one. Here:

• το καινούριο φόρεμά της = her new dress

This is the normal Greek way to say it:

• article + adjective + noun + possessive

So:

• το καινούριο φόρεμά της
• η μεγάλη τσάντα μου
• ο παλιός φίλος του

Even though English says her new dress, Greek normally includes the article.

Καινούριο agrees with φόρεμα, which is a neuter singular noun.

So the adjective must also be neuter singular:

• καινούριος for masculine
• καινούρια / καινούρια for feminine
• καινούριο for neuter

Examples:

• ο καινούριος φίλος
• η καινούρια φίλη
• το καινούριο φόρεμα

In the sentence, φόρεμα is neuter singular, so καινούριο is the correct form.

This is a very common Greek accent pattern.

The basic noun is:

• φόρεμα

But when it is followed by an enclitic like μου, σου, του, της, Greek often adds or shifts an accent:

• το φόρεμά μου
• το φόρεμά σου
• το φόρεμά της

So:

• φόρεμά της = her dress

This extra accent helps maintain the correct stress pattern in pronunciation. It is not a different word; it is the same noun written according to Greek accent rules when followed by an enclitic pronoun.

They are both weak possessive/object pronouns, but they refer to different people.

• μου = my / me
• της = her / to her

So:

• Η φίλη μου = my friend
• το φόρεμά της = her dress

In this sentence:

• μου refers to the speaker
• της refers to the friend

So the whole sentence means that my friend wore shoes with her own new dress.

Grammatically, yes, it could in a different context, because της just means her. But in this sentence, the most natural interpretation is that της refers back to η φίλη μου.

So readers will normally understand:

• my friend ... with her new dress

If Greek wanted to make reference to someone else very clear, it would usually use extra context or a fuller phrasing.

Greek word order is more flexible than English word order.

The sentence:

• Η φίλη μου φόρεσε μπεζ παπούτσια με το καινούριο φόρεμά της.

is the most neutral and natural order.

But Greek could move parts around for emphasis, for example:

• Μπεζ παπούτσια φόρεσε η φίλη μου με το καινούριο φόρεμά της. This emphasizes beige shoes.

Or:

• Με το καινούριο φόρεμά της φόρεσε μπεζ παπούτσια η φίλη μου. This emphasizes with her new dress.

So the given order is natural, but not the only possible one.

Φίλη means female friend. In many contexts that is all it means.

However, just as in many languages, context can sometimes make relationship meanings more specific. But by itself here, the normal reading is simply:

• my female friend

If the sentence had φίλος, that could mean:

• male friend and in some contexts also boyfriend

But φίλη here is best understood simply as female friend.

Yes, these are variant forms of the same adjective meaning new.

You may see:

• καινούριος / καινούρια / καινούριο and also
• καινούργιος / καινούργια / καινούργιο

Both are common in Modern Greek. The sentence uses καινούριο, which is completely normal.

Then Greek would normally use the article:

• Η φίλη μου φόρεσε τα μπεζ παπούτσια με το καινούριο φόρεμά της.

Compare:

• μπεζ παπούτσια = beige shoes
• τα μπεζ παπούτσια = the beige shoes

So the original sentence sounds more like introducing the shoes as an indefinite item of clothing, not previously identified.
