What is a modern alternative to net curtains?

There are many options if you’re not sure about net curtains.

 Voiles are a different type of semi-transparent fabric that normally have a softer drape and which can come in natural fabrics as well as polyester. They also come in many colours while still remaining a sheer fabric.

Daylight blinds are semi-transparent blinds that work in place of nets. Normally of a thicker fabric they are ideal if you dislike drape and want a flat fabric for privacy.

A final option is window cling. This is great if you have an awkward shaped window. Sticking directly to the window using just water, and easy to peel off they can be cut to almost any shape.
