La falda azul queda bien con la camisa blanca.

In this sentence, quedar bien con means to go well with or to match well with.

So La falda azul queda bien con la camisa blanca means that the blue skirt and the white shirt look good together.

Be careful: quedar has many meanings in Spanish depending on context. It can mean things like:

• to stay
• to be left/remain
• to arrange to meet
• to suit/look good

Here, it has the idea of suiting or looking good together.

Because the grammatical subject is la falda azul, which is singular.

Spanish verbs agree with the subject:

• La falda azul queda bien... = singular
• Las faldas azules quedan bien... = plural

Even though the sentence mentions two clothing items, the verb agrees only with the thing that is doing the going well with the other item. In this sentence, that is la falda azul.

In Spanish, descriptive adjectives usually come after the noun.

So:

• falda azul = blue skirt
• camisa blanca = white shirt

This is the normal position for colours and many other descriptive adjectives.

English usually puts adjectives before the noun, but Spanish often puts them after.

Because not all Spanish adjectives behave the same way.

• blanco/blanca/blancos/blancas changes for gender and number
• azul changes for number, but not for gender

So you get:

• la camisa blanca
• el pantalón blanco
• la falda azul
• el vestido azul
• las faldas azules

So azul stays the same in masculine and feminine singular, but becomes azules in the plural.

Spanish uses articles much more often than English does.

So when talking about clothing items in a general or specific outfit context, Spanish normally says:

• la falda
• la camisa

Even where English might say Blue skirt goes well with white shirt, Spanish usually prefers La falda azul queda bien con la camisa blanca.

Leaving out the articles here would sound unnatural in normal Spanish.

Yes. La falda azul combina bien con la camisa blanca is also correct and very natural.

There is a slight difference in feel:

• quedar bien con = to look good with, to suit well with
• combinar bien con = to match well with

In many everyday situations, they are very close in meaning.

No. Quedar bien is used in several related ways.

For example:

• La falda te queda bien. = The skirt looks good on you / suits you.
• Ese color te queda bien. = That colour suits you.
• La falda azul queda bien con la camisa blanca. = The blue skirt goes well with the white shirt.

So quedar bien can mean:

• something suits a person
• something looks good
• one thing goes well with another

Good question. When quedar bien means to suit someone, you often use an indirect object pronoun:

• La falda te queda bien.
• La camisa le queda bien.

But in your sentence, the idea is not that the skirt suits a person. It is that the skirt goes well with the shirt.

So Spanish simply says:

• La falda azul queda bien con la camisa blanca.

No indirect object pronoun is needed because no person is being mentioned.

Yes, absolutely.

That would also be correct:

• La camisa blanca queda bien con la falda azul.

The meaning is basically the same. The difference is mainly about focus:

• La falda azul queda bien con la camisa blanca focuses first on the skirt.
• La camisa blanca queda bien con la falda azul focuses first on the shirt.

Not usually in this context.

Está bien con does not normally mean goes well with when talking about clothes matching. It would sound unnatural here.

For clothes and colours, Spanish commonly uses:

• queda bien con
• combina bien con
• in Spain also often va bien con

For example:

• La falda azul va bien con la camisa blanca.

That is also very natural in Spain.

Con means with.

So:

• queda bien con la camisa blanca = goes well with the white shirt

It links the first item to the second item it matches.

This is very similar to English go well with.

It can mean either, depending on context.

Most naturally, it suggests that the blue skirt and the white shirt look good together as an outfit. That may include:

• colour
• style
• overall appearance

It is not limited strictly to colour theory.

You would need to change the nouns, articles, adjectives, and sometimes the verb.

For example:

• Las faldas azules quedan bien con las camisas blancas.

Changes:

• la → las
• falda → faldas
• azul → azules
• queda → quedan
• camisa → camisas
• blanca → blancas

This is a good example of how much agreement Spanish uses.
