Learn English – Difference in usage between “with” and “in” when describing clothing

Strictly speaking, the two sentences mean the same thing. However, the sentence "Each apple is red" is slightly unusual, and the more natural way to express this would be "Every apple is red", or "All apples are red."

The reason is that the word each is generally used in situations where we consider the apples individually or sequentially, whereas every and all are used for generalizations. So we might say:

We spray-painted each apple red.

Here each is appropriate because every apple was painted individually. However, most people wouldn't say the following:

[?] Each apple turned red by October.

This isn't technically wrong, but it sounds unnatural. Much more usual would be to say one of the following:

Every apple turned red by October.

All the apples turned red by October.

Clothes are those items you wear.

Clothing is pretty much the same, but it seems it can refer to a special type of clothes (the type it refers to depends on the context).

You can see a useful note on the OALD that I'll paste here for future reference:

Clothes or clothing?

Clothing is more formal than clothes and is used especially to mean ‘a particular type of clothes’. There is no singular form of clothes or clothing: a piece/an item/an article of clothing is used to talk about one thing that you wear such as a dress or shirt.
