Describing people with 'au', 'à la' and 'aux', as in 'la fille aux yeux bleus'
When English picks someone out by their looks, it uses with: the girl with blue eyes, the man with a beard, the lady with the hat. French has a neat construction for this: the preposition à followed by the definite article. So you get la fille aux yeux bleus, l'homme à la barbe and la dame au chapeau. It works with body features such as cheveux, yeux or moustache, and with clothes and accessories such as lunettes or robe.
English speakers trip over this for two reasons. First, they expect avec because it translates with. Second, the article feels odd: English says a beard, but French says la barbe. Avec is not wrong, but à plus the article is the natural, idiomatic way to name the feature that identifies someone.

How it works
The pattern is: person + à + definite article + feature (+ adjective). The usual contractions apply: à + le becomes au, à + les becomes aux, à la stays as it is, and à l' is used before a vowel.
au: l'homme au chapeau
à la: la femme à la robe rouge
à l': la fille à l'écharpe verte
aux: le garçon aux cheveux courts
The definite article is there because French treats the feature as the one that singles the person out. Think of it as "the man of the beard" rather than "a man who has a beard". The whole group works like a label, which is why you hear it in descriptions, stories, fairy tales and when pointing someone out in a crowd.
C'est la fille aux yeux verts.
(That's the girl with green eyes.)
Je cherche un homme à la barbe rousse.
(I'm looking for a man with a red beard.)
The words
Hair and facial hair
These are the classic identifiers: cheveux (always plural here, so aux), barbe, moustache and the hairstyle queue-de-cheval.
L'homme aux cheveux longs joue de la guitare.
(The man with long hair is playing the guitar.)
Le monsieur à la moustache grise est mon voisin.
(The gentleman with the grey moustache is my neighbour.)
La petite à la queue-de-cheval s'appelle Léa.
(The little girl with the ponytail is called Léa.)
The face
Remember that œil becomes yeux in the plural, so it is almost always aux yeux. The same goes for nez, visage, figure, bouche, lèvre (usually aux lèvres), oreille, sourcil, joue and menton. They usually take an adjective: au nez pointu, aux sourcils épais, au menton carré.
Une femme au visage souriant m'a ouvert la porte.
(A woman with a smiling face opened the door for me.)
Sur la photo, il y a un bébé aux joues toutes rouges.
(In the photo there's a baby with bright red cheeks.)
Body, skin and voice
Use the same pattern with peau, voix, main, épaule, jambe and bras: à la peau mate, aux mains fines, au bras cassé.
J'adore ce chanteur à la voix grave.
(I love that singer with the deep voice.)
Un grand type aux larges épaules est entré.
(A tall guy with broad shoulders came in.)
Clothes and accessories
What someone wears works just as well, as long as it marks them out: lunettes, lunettes de soleil, chapeau, casquette, manteau, robe, écharpe and foulard. Words like parapluie or sac rouge behave the same way.
Tu vois la dame aux lunettes rondes ?
(Do you see the lady with the round glasses?)
Le garçon à la casquette est mon cousin.
(The boy in the cap is my cousin.)
Watch out
This construction only describes a noun: it comes right after the person. To state a feature in a full sentence, French uses avoir with the definite article. You say elle a les yeux bleus, never elle est aux yeux bleus.
Ma sœur a les cheveux frisés.
(My sister has curly hair.)
Avec is still correct, especially with an indefinite article for a plain description: un homme avec une barbe. Choose à plus the definite article when the feature is the label that identifies the person. Also keep the article: un homme à barbe exists, but it means a bearded type of man in general, not the man with the beard you are pointing at.
Summary
To pick someone out by a feature or something they wear, put au, à la, à l' or aux plus the feature right after the person, where English uses with: la fille aux yeux bleus, l'homme au chapeau. In a full sentence about that feature, switch to avoir with the definite article: elle a les yeux bleus.
