When a jumper (sweater) is washed, it absorbs water which adds weight to the garment. The water molecules fill the spaces in the fabric, increasing the overall mass of the jumper. Additionally, wet fabric tends to cling closer to the body, giving the sensation of heaviness as it is worn.
The jumper probabaly retained water in the fabric and all the extra water makes it heavier. Once it dries it should feel the same.
When you wash a jumper, water and detergent are absorbed into the fibers, adding weight to the garment. The damp fabric can feel heavier until it dries out completely. Additionally, the agitation and spinning in the washing machine can compact the fibers, making the garment denser and heavier.
Put on a jumper
Some dumbbells feel heavier than others because they have different weights. The weight of a dumbbell is determined by the amount of material it is made of, so a heavier dumbbell will feel heavier to lift than a lighter one.
Some weights feel heavier than others because of their mass and density. The more mass and density a weight has, the more force is required to lift it, making it feel heavier.

Astronauts feel heavier during launch because of the upward motion of the spacecraft. This has the effect of adding extra "g's," or gravity forces, making everything seem heavier while the thrust is occurring.

Iron plates feel heavier than other materials because iron is a dense metal, meaning it has more mass packed into a smaller volume compared to other materials. This density makes iron plates feel heavier when lifted or carried.
-- You feel lighter on a roller coaster when your speed is either upward and decreasing or downward and increasing. -- You feel heavier when your speed is either upward and increasing or downward and decreasing. -- Exactly the same as on an elevator.
Metal plates feel heavier than other materials because metals are denser and have a higher mass per unit volume compared to other materials. This means that for a given volume, a metal plate will have more mass, resulting in a heavier feel when lifted.
