It can be difficult to tell if a sweater is made from real cashmere just by looking at it, as there are many synthetic materials that can mimic the look and feel of cashmere. However, there are a few things you can look for to help determine if a sweater is made from real cashmere:
1. Check the label: Look for a label that indicates the sweater is made from 100% cashmere or a high percentage of cashmere, such as 95% or more. If the label only says "cashmere blend," it may contain a lower percentage of cashmere or a blend of cashmere and synthetic fibers.

2. Softness and feel: Cashmere is known for its softness and luxurious feel. If the sweater feels rough or scratchy, it may not be made from real cashmere. However, keep in mind that some high-quality cashmere may have a slightly coarser texture.

3. Price: Cashmere is a premium material and is typically more expensive than other types of wool or synthetic fibers. If the price seems too good to be true, it may not be real cashmere.
4. Pilling: Cashmere is prone to pilling, which is when small balls of fuzz form on the surface of the sweater. If the sweater doesn't pill at all, it may not be made from real cashmere.

Keep in mind that these are just guidelines and the best way to ensure that a sweater is made from real cashmere is to purchase it from a reputable retailer or brand that specializes in cashmere products.
