Bol kesimli kıyafette kullanım izi bulundu.

Bol kesimli means loose-cut, loose-fitting, or with a roomy fit.

• bol = loose, wide, roomy
• kesim = cut, fit, tailoring/style of a garment
• -li = having, with

So bol kesimli kıyafet is clothing that has a loose fit.

Kesimli is built from the noun kesim plus the suffix -li.

• kesim = cut, style, fit
• -li = having, with

So kesimli literally means having a certain cut/style.

In clothing language, Turkish often uses this pattern:

• dar kesimli = slim-cut / tight-fitting
• rahat kesimli = comfortable-cut / relaxed fit
• bol kesimli = loose-cut

Because the word takes the locative suffix, and that suffix changes form according to Turkish sound rules.

The basic locative suffix is:

• -de / -da / -te / -ta

In kıyafette:

• the last vowel in kıyafet is e, so the vowel in the suffix is e
• the word ends in t, which is a voiceless consonant, so the suffix starts with t, not d

So:

• kıyafet + te = kıyafette

This means in/on the clothing or on the garment, depending on context.

It is the locative case, which usually means in, on, at.

Here, kıyafette means something like:

• on the garment
• in the clothing item
• on this piece of clothing

English chooses the preposition more freely, but Turkish uses the locative case for this kind of idea.

It can mean any of those depending on context.

• kıyafet can mean clothes, clothing, outfit, or garment
• in this sentence, it most likely refers to a specific item or outfit being examined

So in English, the best rendering depends on the situation:

• on the loose-fitting garment
• on the loose-cut clothing
• in the loose-fit outfit

Kullanım izi means sign of use, trace of use, wear mark, or evidence that it has been used.

• kullanım = use, usage
• iz = mark, trace, sign

So this phrase refers to some visible indication that the item was previously used.

Because this is a very common Turkish noun compound pattern.

In Turkish, when one noun modifies another noun, the second noun often takes the 3rd person possessive suffix:

• iz → izi

So:

• kullanım izi = use mark / sign of use

This does not necessarily mean literal possession in English. It is just how Turkish commonly forms this kind of compound.

Compare:

• araba kapısı = car door
• okul bahçesi = school yard
• kullanım izi = sign of use

Here bulundu means was found.

It is the past tense form used in a passive or impersonal way, which is very common in reports, inspections, and formal descriptions.

So the sentence has a report-like tone:

• A sign of use was found on the loose-cut garment.

Because kullanım izi is not the direct object here.

In this sentence, the structure is effectively passive:

• A sign of use was found

In an active sentence, you might have:

• Birisi kullanım izini buldu = Someone found the sign of use

There, kullanım izini is the direct object, so it takes the accusative.

But in kullanım izi bulundu, the phrase is the thing that was found, so it appears without the accusative.

The agent is not stated, and that is normal.

Turkish often leaves out who did the action when:

• it is unknown
• it is unimportant
• the sentence is meant to sound objective or report-like

So the sentence focuses on the result, not the finder:

• A sign of use was found

This is similar to English passive style.

Turkish word order is flexible, but the verb usually comes at the end.

Here the order is:

• Bol kesimli kıyafette = on the loose-cut garment
• kullanım izi = a sign of use
• bulundu = was found

This order sounds natural and report-like. It presents the location first, then what was found.

A different order is also possible, for example:

• Kullanım izi bol kesimli kıyafette bulundu.

That version puts a little more emphasis on kullanım izi.

Because Turkish does not have articles like English a/an/the.

Whether something is understood as definite or indefinite usually comes from:

• context
• case marking
• word order
• the situation

So kullanım izi bulundu could be translated as:

• a sign of use was found
• the sign of use was found

In most contexts here, a sign of use was found sounds most natural.

Yes, but it sounds somewhat formal or report-like.

It would fit well in:

• an inspection report
• a product return evaluation
• a police or forensic description
• a resale or condition report

In casual conversation, a speaker might choose something simpler or more conversational, but this sentence is perfectly natural in formal written or official-style Turkish.
