A maquiagem dela ficou bonita, e o batom vermelho combinou com os brincos.

Portuguese uses definite articles much more often than English.

• a maquiagem = the makeup
• o batom = the lipstick
• os brincos = the earrings

In Brazilian Portuguese, it is very normal to use the article even when English would often leave it out. So A maquiagem dela ficou bonita sounds natural, while English would often just say Her makeup looked nice.

Dela means of her / hers / her and is often used to make possession very clear.

• a maquiagem dela = her makeup

Portuguese can also use sua maquiagem, but sua can sometimes be ambiguous, because it might mean his, her, your, or even their, depending on context.
Using dela removes that ambiguity.

So:

• a maquiagem dela = clearly her makeup
• sua maquiagem = could be understood from context, but is less specific by itself

Here, ficou comes from ficar, and it means something like turned out / ended up / looked.

So:

• A maquiagem dela ficou bonita = Her makeup looked nice / turned out nice

This use of ficar is very common in Brazilian Portuguese when talking about how something looks after being done, arranged, prepared, or changed.

Examples:

• O cabelo ficou lindo. = The hair looked beautiful.
• A decoração ficou ótima. = The decoration turned out great.

It is not exactly the same as ser or estar.
Ficou bonita suggests the result or final appearance.

Because bonita agrees with maquiagem, which is a feminine singular noun.

• maquiagem = feminine singular
• therefore: bonita = feminine singular adjective

Agreement is very important in Portuguese.

Compare:

• A maquiagem ficou bonita.
• O batom ficou bonito.

The adjective changes to match the noun.

In Portuguese, adjectives usually come after the noun.

• batom vermelho = red lipstick
• brincos bonitos = beautiful earrings

That is the normal order. Sometimes adjectives can come before the noun, but that often changes the tone or sounds more literary. In this sentence, batom vermelho is the standard and natural order.

Combinar com means to match / to go well with.

So:

• o batom vermelho combinou com os brincos = the red lipstick matched the earrings

The verb is combinar com, so the com is part of the expression. You use it before the thing that matches.

Examples:

• Essa blusa combina com a saia. = This blouse matches the skirt.
• Azul combina com branco. = Blue goes well with white.

So the sentence is structured correctly:

• combinou com os brincos

Because earrings are usually thought of as a pair, and Portuguese normally uses the plural brincos for that.

• o brinco = the earring
• os brincos = the earrings

If someone is wearing two earrings, the normal phrase is os brincos.

Yes, you could, but the meaning changes slightly.

• ficou bonita = it turned out beautiful / it looked beautiful as a result
• estava bonita = it was beautiful / it looked beautiful at that moment

In this sentence, ficou bonita is especially natural because it refers to the result of putting on the makeup. It sounds like: after she did her makeup, the final look was beautiful.

Portuguese often leaves possession implied when the context is clear.

In English, you might say:

• Her makeup looked nice, and her red lipstick matched her earrings.

In Portuguese, once the context is established, repeating the possession can sound unnecessary. So:

• A maquiagem dela ficou bonita, e o batom vermelho combinou com os brincos.

naturally suggests that the lipstick and earrings are also hers.

If you wanted to make it explicit, you could say:

• A maquiagem dela ficou bonita, e o batom vermelho dela combinou com os brincos dela.

But that sounds more repetitive.

Yes. That would also be correct.

• O batom vermelho combinou com os brincos.
• Os brincos combinaram com o batom vermelho.

Both mean that the two items matched each other. The difference is just which item you present first as the subject.

Notice that the verb must agree with the subject:

• o batom combinou
• os brincos combinaram

Here, maquiagem is being used like an uncountable noun, similar to makeup in English.

• A maquiagem dela ficou bonita.

It refers to the overall makeup look, not to individual makeup products.

But Portuguese can also use maquiagens in some contexts, especially when talking about different types, styles, or products of makeup.

Examples:

• Ela comprou várias maquiagens. = She bought various makeup items / makeup products.
• As maquiagens de festa são mais marcantes. = Party makeup styles are more striking.

So in this sentence, it means the overall makeup look.

A helpful approximate pronunciation is:

ma-kee-AH-zhen

A few notes:

• qu in maquiagem sounds like k
• the stressed syllable is a
• the g before e sounds like the s in measure or the zh sound
• the final -em has a nasal sound in Brazilian Portuguese

It will not sound exactly like English, but that approximation can help you get started.
