Na co dzień noszę dżinsy, ale dziś zakładam garnitur.

It means on a day-to-day basis, normally, or in everyday life.

So Na co dzień noszę dżinsy is not just about literal daily repetition; it suggests my usual everyday style/habit is jeans.

A close comparison:

• na co dzień = normally / for everyday use
• codziennie = every day

These are often similar, but na co dzień sounds a bit more like as a rule / in everyday situations.

Because Polish usually leaves out subject pronouns when the verb ending already shows who the subject is.

• noszę = I wear
• zakładam = I put on / I am putting on

The -ę and -am endings tell you the subject is I.

You can add ja for emphasis:

• Ja na co dzień noszę dżinsy, ale dziś zakładam garnitur.

That would sound more like I wear jeans normally, but today I’m the one putting on a suit.

Noszę is the 1st person singular present tense of nosić.

Dictionary form:

• nosić = to wear, to carry, to have on regularly

In clothing contexts, nosić usually means to wear habitually / to wear as a regular item, not necessarily the act of putting it on at that moment.

So:

• noszę dżinsy = I wear jeans / I usually wear jeans

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

Polish uses two different ideas:

• nosić = to wear habitually / to have as regular clothing
• zakładać = to put on

So the contrast is:

• Na co dzień noszę dżinsy = I usually wear jeans
• ale dziś zakładam garnitur = but today I’m putting on a suit

This sounds natural because the first half describes a general habit, while the second half describes a specific action/choice today.

If you wanted to focus more on the state of already wearing the suit, Polish might also say things like:

• Dziś mam na sobie garnitur = Today I have a suit on
• Dziś jestem w garniturze = Today I’m in a suit

Because Polish does not have a separate tense form like the English present continuous.

Polish present tense can cover:

• general habits
• actions happening now
• current situations
• near-future plans, depending on context

Here, the time expressions do the work:

• na co dzień tells you it is a habit
• dziś tells you it is today’s specific situation

So Polish does not need a special am wearing form.

Because dżinsy works like English jeans: it is normally used as a plural noun.

So Polish usually treats it as a plural item of clothing:

• te dżinsy = these jeans
• noszę dżinsy = I wear jeans

This is very common with clothes that are thought of as having two legs or two matching parts.

Also, in this sentence dżinsy is the direct object, and for this kind of inanimate plural noun, the accusative form is the same as the nominative form, so it stays dżinsy.

Because garnitur is a masculine inanimate noun, and in the singular its accusative is the same as its nominative.

After zakładam you need the direct object, which means the accusative case:

• zakładam garnitur = I am putting on a suit

But because garnitur is masculine inanimate, the form does not change.

Compare:

• nominative: to jest garnitur = this is a suit
• accusative: zakładam garnitur = I’m putting on a suit

Both are in the accusative, because they are the direct objects of the verbs:

• noszę co? → dżinsy
• zakładam co? → garnitur

So the hidden grammar question is what do I wear? what do I put on?

Forms here:

• dżinsy = accusative plural, same shape as nominative
• garnitur = accusative singular, same shape as nominative because it is masculine inanimate

Yes. Dziś and dzisiaj both mean today.

Examples:

• Dziś zakładam garnitur.
• Dzisiaj zakładam garnitur.

Both are correct and natural.
Dziś is simply shorter and a bit more compact in style.

No, Polish word order is fairly flexible.

The given sentence:

• Na co dzień noszę dżinsy, ale dziś zakładam garnitur.

is very natural and emphasizes the time expressions na co dzień and dziś.

You could also say:

• Noszę na co dzień dżinsy, ale dziś zakładam garnitur.

That is also correct, but the emphasis shifts slightly.

In Polish, changing word order often changes focus rather than the basic meaning.

Roughly like JEEN-sih.

A few details:

• dż sounds like the j in jam
• i sounds like ee
• y is a Polish sound that is a bit like a short, relaxed i, but not exactly English ee

So dżinsy is close to English jeans, with an extra Polish ending.

Yes, you could, and it would be correct:

• Codziennie noszę dżinsy = I wear jeans every day

But it is not exactly the same in nuance as Na co dzień noszę dżinsy.

• codziennie stresses every single day
• na co dzień stresses normally / as everyday wear / as my usual style

So in this sentence, na co dzień is a good choice because it contrasts nicely with dziś:

• normally I wear jeans
• today I’m putting on a suit
