Bu kostüm sana çok yakışıyor.

Yakışıyor comes from the verb yakışmak, which means to suit, to look good on, or to be becoming to someone.

So Bu kostüm sana çok yakışıyor means something like:

• This costume suits you very well
• This costume looks great on you

It is commonly used for clothes, colors, hairstyles, accessories, and even some behaviors or roles.

Because yakışmak uses the dative case in Turkish.

• sen = you
• sana = to you / on you

With yakışmak, Turkish says something more like it suits to you rather than it suits you.

So:

• Bu kostüm sana yakışıyor = This costume suits you

Not:

• Bu kostüm seni yakışıyor ✘

A useful pattern to remember is:

• Bu bana yakışıyor = This suits me
• Bu sana yakışıyor = This suits you
• Bu ona yakışıyor = This suits him/her/it

The ending -yor is the Turkish present continuous tense marker.

So:

• yakışmak = to suit
• yakışıyor = is suiting / suits

In Turkish, this form is very often used where English would simply use the present tense.

So even though yakışıyor literally looks like is suiting, it is naturally translated as:

• it suits
• it looks good on

That is completely normal in Turkish.

Here is the sentence piece by piece:

• Bu = this
• kostüm = costume
• sana = to you / on you
• çok = very
• yakışıyor = suits / looks good

So the structure is:

Bu kostüm + sana + çok + yakışıyor
This costume + to you + very + suits

A very literal translation would be:

This costume suits you very much

But natural English is:

This costume suits you very well
or
This costume looks great on you

Yes, it is a very natural word order.

Turkish word order is flexible, but this version sounds neutral and standard.

You may also hear:

• Bu kostüm çok yakışıyor sana
• Sana bu kostüm çok yakışıyor

These are all possible, but the emphasis changes slightly.

For example:

• Sana bu kostüm çok yakışıyor puts more focus on you
• Bu kostüm sana çok yakışıyor is a straightforward, neutral statement

Çok means very or a lot.

In this sentence, it strengthens yakışıyor:

• Bu kostüm sana yakışıyor = This costume suits you
• Bu kostüm sana çok yakışıyor = This costume suits you very well

So çok makes the compliment stronger.

No. It is very common with clothes, but not limited to them.

You can use yakışmak for:

• clothes
  
  • Bu elbise sana yakışıyor. = This dress suits you.
• colors
  
  • Mavi sana yakışıyor. = Blue suits you.
• hairstyles
  
  • Kısa saç sana çok yakışmış. = Short hair suits you very well.
• accessories
  
  • Bu gözlük sana yakışıyor. = These glasses suit you.
• roles or behavior
  
  • Babalık sana yakışıyor. = Fatherhood suits you.

So it has a broad meaning: something looks right, fitting, or attractive on someone.

The dictionary form is yakışmak.

In this sentence, it is conjugated in the third person singular present continuous because the subject is bu kostüm.

Conjugation:

• Ben yakışıyorum = I suit / I am suiting
• Sen yakışıyorsun = you suit
• O yakışıyor = he/she/it suits
• Biz yakışıyoruz = we suit
• Siz yakışıyorsunuz = you suit
• Onlar yakışıyor / yakışıyorlar = they suit

Here:

• subject = Bu kostüm
• verb form = yakışıyor

So: This costume suits...

Here are some useful versions:

Past

• Bu kostüm sana çok yakıştı. = This costume suited you very well.

Negative

• Bu kostüm sana yakışmıyor. = This costume doesn’t suit you.

Question

• Bu kostüm sana yakışıyor mu? = Does this costume suit you?

Past negative

• Bu kostüm sana yakışmadı. = This costume didn’t suit you.

These are very useful patterns to learn with yakışmak.

A rough pronunciation guide is:

Boo kostoom sah-nah chok yah-kuh-shuh-yor

A few sounds to notice:

• Bu = boo
• ü does not appear here, but u is a normal oo sound
• çok = chok
• ş = sh
• ı in yakışıyor is a Turkish sound with no exact English equivalent; it is like a relaxed, unrounded vowel

So yakışıyor is approximately:

yah-kuh-shuh-yor

Not perfect English spelling, but close enough to help.

Yes, definitely.

Bu kostüm sana çok yakışıyor is a warm, natural compliment. It sounds kind and idiomatic, not overly formal.

You can use it in everyday situations when someone is wearing:

• a costume
• a dress
• a shirt
• a jacket
• a color
• a new style

It is a very useful sentence pattern in Turkish for giving compliments naturally.
