Learn Spanish (Spain): Siempre llevas la misma camisa.

In Spanish, llevar is the standard verb used to say that someone is wearing an item of clothing, an accessory, or even a certain hairstyle. You can think of it as 'carrying' clothes on your body.

Why does the adjective misma come before the noun camisa? Don't Spanish adjectives usually go after the noun?

You are right that most descriptive adjectives go after the noun. However, adjectives that specify which one or how many, like mismo (same), almost always go before the noun.

Does misma change its ending depending on the clothing item?

Yes! Mismo must match the gender and number of the noun it describes. Because camisa is feminine and singular, it becomes la misma camisa. If it were a masculine word like vestido (dress), you would say el mismo vestido.

Where is the word for 'you' in this sentence?

In Spanish, the subject pronoun (tú) is usually dropped. The -as ending on llevas already makes it perfectly clear who is doing the action. Adding tú here (Tú siempre llevas...) is grammatically correct but would add a strong, slightly accusatory emphasis to the word 'you'.
