The Blush BiBi pearl and rhinestone sweater comes in S, M, L and XL. Its chart does not increase every measurement at every letter. If your concern is whether a sleeve will reach your wrist under a jacket, read that column separately from bust room.

Two length plateaus, four bust figures

S is listed at 42 inches bust and M at 44, yet both have a 19-inch sleeve, 25-inch top length and 21-inch shoulder. L moves to 46 inches bust, 20 inches sleeve, 26 inches length and 22 inches shoulder. XL reaches 48 inches bust while the other three values remain the same as L. So M may change chest room without changing the listed reach or hem; XL does the same relative to L. The larger jump in sleeve, shoulder and top length occurs between M and L.

Use an owned knit and coat as reference

Lay a sweater that works under your coat flat and record its bust, shoulder, sleeve and length using the same measuring route. The listing does not say where its sleeve measurement starts or whether bust is a finished garment circumference. If those numbers decide your size, request a flat-lay measurement of your chosen option. Also check the selected photos for where the pearl and rhinestone decoration sits; the text names the decoration but does not map it across the front or sleeves.

The page lists 62% acrylic and 38% polyester, slight stretch, machine wash cold and tumble dry low. Those are label-style instructions, not a test of how this specific decoration holds up. For a garment you would wear against a coat or bag strap, inspect the decoration placement in the photos and follow the garment care label when it arrives.
