Les bottines marron sont jolies, mais les chaussures beiges vont mieux avec ton manteau.

Because both noun phrases are plural and definite: les bottines = the ankle boots, and les chaussures = the shoes.

French usually repeats the article before each noun phrase, even when English might sound fine with just one in a shorter list. Here, the sentence is really comparing the brown ankle boots with the beige shoes, so each group gets its own article.

Both nouns are plural.

• une bottine = one ankle boot

• des bottines / les bottines = ankle boots / the ankle boots

• une chaussure = one shoe
• des chaussures / les chaussures = shoes / the shoes

The sentence talks about more than one boot and more than one shoe, so both nouns take the plural -s.

Because marron is one of those French color words that is often treated as invariable when it comes from a noun. Originally, marron means chestnut.

So you usually say:

• des bottines marron
• des yeux marron

not marrons as a color adjective.

This is a common point learners notice because many other adjectives do agree, but some color terms like marron often stay unchanged.

Because beige is a regular adjective, so it agrees in number with the noun it describes, while marron often stays invariable as a color term.

Here:

• chaussures is plural
• so beige becomes beiges

Compare:

• une chaussure beige
• des chaussures beiges

But:

• une bottine marron
• des bottines marron

So this sentence is a nice example of two different adjective patterns.

Because jolies agrees with les bottines, which is feminine plural.

The basic adjective is joli. Its forms are:

• masculine singular: joli
• feminine singular: jolie
• masculine plural: jolis
• feminine plural: jolies

Since bottines is feminine plural, the correct form is jolies.

Because jolies is not directly attached to the noun inside the noun phrase here. It comes after sont because it is a predicate adjective.

Structure:

• Les bottines marron = subject
• sont = are
• jolies = adjective describing the subject after the verb

So this works like:

• Les bottines sont jolies.
• The boots are pretty.

By contrast, an adjective directly before or after a noun inside the noun phrase would be something like:

• de jolies bottines
• des bottines jolies (less natural here)

Yes. In French, aller avec can mean to go with in the sense of to match or to suit.

So:

• Ces chaussures vont avec la robe = These shoes go with the dress.
• Ces chaussures vont mieux avec la robe = These shoes go better with the dress.

Here, vont mieux avec ton manteau means the beige shoes are a better match for your coat.

Because mieux is the comparative form of bien, just like better is the comparative of well in English.

• bien = well
• mieux = better

So French says:

• Ça va bien. = It goes well.
• Ça va mieux. = It goes better / It’s better.

In this sentence, vont mieux avec means go better with or match better with.

Because manteau is a masculine singular noun.

French possessive adjectives agree with the thing possessed, not with the owner.

So:

• ton manteau = your coat
• ta veste = your jacket
• tes chaussures = your shoes

Even if the person being addressed is female, you still say ton manteau, because manteau itself is masculine.

It follows a very normal French sentence pattern:

• subject: Les bottines marron
• verb: sont
• adjective/complement: jolies

Then the second clause begins with mais = but:

• les chaussures beiges
• vont mieux avec ton manteau

So the structure is:

[subject] + [verb] + [description], mais [subject] + [verb phrase] + [complement]

This is very standard French word order and matches natural English order fairly closely.

Mais is the normal, neutral word for but. It introduces a contrast:

• the brown ankle boots are pretty
• however, the beige shoes match your coat better

So the speaker is not saying the boots are bad. They are saying that, despite being pretty, the beige shoes are the better choice with that coat.

Yes. Joli/jolie often means pretty, nice-looking, or lovely, depending on context.

With clothing, jolies can sound a bit broader than just physical beauty. It can suggest that the boots are attractive, tasteful, or pleasing in appearance.

So a learner should not always force a single English word; jolies often sits somewhere between pretty and nice.

A few things may stand out:

• Les is usually pronounced lay
• bottines sounds roughly like bo-teen
• marron has a nasal ending
• sont also has a nasal vowel and the final t is silent
• jolies sounds roughly like zho-lee
• beiges sounds like beige with the plural -s silent
• ton manteau has nasal vowels in both words

Also, many final plural -s endings are not pronounced, so the plural is often heard from the article or the overall sentence rather than from the noun ending itself.
