For a starter kit, look for a lightweight, collapsible light stand that’s inexpensive but reasonably stable; air-cushioning is a nice bonus. Several users report good results with budget Impact stands, and similar compact stands are popular because they fit easily in a tripod bag with an umbrella swivel.

You’ll also need an umbrella bracket/swivel with a hot shoe mount. A basic umbrella adapter is enough to get your speedlight and umbrella positioned properly.

For the umbrella itself, inexpensive models are usually fine. Many people start with a white shoot-through umbrella, and a dual-purpose shoot-through/reflective umbrella can be a flexible choice. Sizes around the small-to-medium range are common for portraits and headshots.

Whatever stand you choose, stability matters: add a sandbag or weight, especially outdoors or in busy areas, because umbrella setups can tip or blow over easily.

In short: buy a cheap collapsible stand, a simple umbrella swivel/hot-shoe adapter, and an inexpensive shoot-through or convertible umbrella. That’s a practical, portable entry point, and you can upgrade later if needed.
