Learn Italian: I modelli per la sfilata sarebbero pronti domani. - The designs for the fashion show would be ready tomorrow.

Sarebbero means "they would be". It is the present conditional of the irregular verb essere (to be). Instead of using its normal root, essere uses the irregular stem sar- for the conditional. We then add the "they" (loro) ending -ebbero to get sarebbero.

Why use the conditional sarebbero (would be) instead of the future tense (will be)?

Using the conditional sarebbero rather than the future tense saranno (they will be) adds a feeling of uncertainty or a hidden condition. It implies the designs would be ready tomorrow, but only if everything goes according to plan or if someone finishes their work in time.

Why does modelli mean "designs" in this sentence instead of "models" (the people)?

The word modello has a few different meanings depending on the context. While it can refer to a fashion model (the person), it also commonly means a design, pattern, or prototype. Here, talking about things being "ready tomorrow" for a fashion show (sfilata), "designs" makes the most sense.
