Mi hija lleva una coleta alta para ir a la escuela.

Because llevar has more than one common meaning. Besides to carry or to take, it also means to wear or to have on.

In this sentence, lleva una coleta alta means:

• she wears a high ponytail
• or more naturally in English, she has her hair in a high ponytail

This use of llevar is very common with:

• clothes: lleva una chaqueta
• accessories: lleva gafas
• hairstyles: lleva coleta

In Spain, coleta means ponytail.

So una coleta alta is a high ponytail.

A useful regional note:

• In Spain, coleta is very common.
• In many parts of Latin America, people more often say cola de caballo.

So this sentence sounds especially natural for Spanish from Spain.

Because adjectives in Spanish usually agree with the noun they describe.

Here:

• coleta is a feminine singular noun
• so the adjective must also be feminine singular
• that gives us alta

So:

• un moño alto
• una coleta alta

In Spanish, most descriptive adjectives normally come after the noun.

So:

• una coleta alta = a high ponytail

That is the neutral, standard order.

If you put the adjective before the noun, it often sounds more literary, emphatic, or stylistically marked. For a basic description, coleta alta is the normal choice.

Because in Spanish, singular countable nouns usually need an article or another determiner.

So Spanish prefers:

• lleva una coleta alta

English often drops the article in similar phrases, but Spanish usually does not.

Also, una here introduces the hairstyle as a high ponytail, not as some specific previously mentioned ponytail. It is just describing what hairstyle she wears.

It can do either, depending on context.

The Spanish present tense often covers both:

• right now
• habitually / generally

In this sentence, because of para ir a la escuela, the most likely meaning is habitual:

• My daughter wears a high ponytail to school

But in the right context, it could also describe what she is wearing today.

After para, Spanish normally uses the infinitive when the subject is the same.

Here, the daughter is both:

• the one who wears the ponytail
• and the one who goes to school

So Spanish uses:

• para ir a la escuela = to go to school / in order to go to school

You would not say para va because after a preposition like para, you do not use a conjugated verb by itself.

A structure with para que is used when there is a new subject or when a full clause is needed, for example:

• Lo hace para que su hija vaya cómoda.

Because escuela is a noun that normally takes an article in this expression.

So:

• ir a la escuela
• ir al colegio
• ir a la universidad

English says go to school without an article, but Spanish usually keeps the article here.

So a la escuela is completely normal.

The sentence is correct, but in Spain, for a child, colegio is often more common in everyday speech than escuela.

So a very natural Spain-Spanish version would be:

• Mi hija lleva una coleta alta para ir al colegio.

Both are understandable and correct, but colegio may sound more typical for a school a child attends.

Yes, absolutely. That version is also very natural.

Compare:

• Mi hija lleva una coleta alta
• Mi hija lleva el pelo en una coleta alta

The second version makes the hair idea more explicit:

• literally, My daughter wears her hair in a high ponytail

The original sentence is still perfectly fine, especially because coleta already clearly suggests a hairstyle.

It is possible in some contexts, but llevar is much more natural here.

For clothing, accessories, and hairstyles, Spanish usually prefers llevar:

• lleva gafas
• lleva sombrero
• lleva coleta

Usar often sounds more like to use, and with appearance it can feel less idiomatic. So for a learner, llevar is the best choice in this sentence.
