The Mushroom asymmetrical open-stitch sweater has a loose shape, distressed details, a round neck and half sleeves. Its open stitches make the shirt underneath part of what you see. Decide where you want that layer visible before treating a size label as the whole decision.

Map the areas that need coverage

Start with a top you already own. Put it on and mark the neckline, shoulder and side areas you want covered. Compare those areas with the sweater photos for the selected size. The listing does not locate or measure every open stitch, so request front, back and side images against a plain background if placement matters. A close-fitting base layer may keep the two necklines distinct; a loose one may show through as a second texture. These are outfit choices to test, not claims about the sweater’s opacity.

Use the chart for the right purpose

The published S, M and L rows say bust 34–36, 37–38 and 39–40 in, with waist ranges 26–28, 29–31 and 32–33 in. These appear as product measurements in the listing, but their body-style intervals do not tell you the finished sweater width. Ask for the laid-flat underarm width, hem width and front and back lengths in your intended size. Doubling a confirmed flat width gives an approximate circumference; do not double the published bust range unless the seller confirms how it was measured.

Check the asymmetry against a reference

Lay a loose sweater that fits you over the chosen underlayer. Compare its shoulder-to-hem length at both sides and the opening around your upper arm. Ask how far this item’s hem drops from its shorter side to its longer side, and for the sleeve opening. A half sleeve leaves the lower arm exposed, while the loose, distressed construction may reveal more of the base layer as you move. The page lists slight stretch without a measured stretch range, so a still photo cannot settle that fit question.

The stated composition is 55% cotton and 45% acrylic. The care line says machine wash cold and tumble dry low. Check the garment label on arrival, especially around distressed openings. The listing provides no wash-test results or measured change in shape.
