The oversized rib-trim sweatshirt lists S through 2XL in Black, Olive and Khaki. If you want a relaxed fit, the garment chart is more useful than choosing the largest familiar letter. It lists bust, shoulder, sleeve, body length and hem width, but does not explain every measuring convention.

Read shoulder and sleeve together

At S the published shoulder is 29.7 in and sleeve length is 19.9 in; at 2XL they are 35.2 and 20.7 in. The shoulder figure changes by 5.5 in, while the sleeve figure changes by only 0.8 in. With a broad dropped shoulder, sleeve length starts farther down the arm than on a conventional shoulder-seam top. Do not compare its sleeve number alone with a fitted sweatshirt. Compare the complete shoulder-to-cuff reach on a garment whose sleeve position you like, and ask where the seller starts each measurement.

Decide where the body ends

The listed bust rises from 45.7 to 56.7 in across S–2XL, a difference of 11.0 in. Hem width rises from 40.9 to 52.0 in, while length moves from 29.5 to 32.7 in. Sizing up for more chest room therefore also gives a wider, lower hem. Compare those points with a sweatshirt you wear over the same trousers or skirt; a longer hem may change the proportion of the outfit even when the bust fits.

The source lists 75% polyester and 25% cotton, calls the fabric non-stretch and says the body is unlined. It does not specify fabric weight or a warmth rating. Use the actual garment numbers and your preferred layer as the decision basis, and request clarification on whether the published bust and hem widths represent full circumferences before comparing them directly with body measurements.
