Questions about this piece
Do you tuck in an oversized sweater?
Usually just the front, and only part of it. Tucking the whole thing in fights the volume and bunches at the waistband, while leaving it all out can swallow the line of your body. Pushing the front few inches into a waistband shows where your waist is and lets the back and sides keep their shape. This one is cut loose, so a front tuck is the quickest way to put a waistline back into it.
What is a dropped shoulder?
A shoulder seam that sits out on the upper arm instead of on the bony point of your shoulder. It is a deliberate cut, not a sizing mistake: moving the seam outward widens the top of the garment and lets the sleeve hang in a soft line rather than at a set angle. It also means the knit reads roomier than the size on the tag suggests, and that lifting your arms pulls the whole body up instead of just the sleeve. This sweater is built that way, with a round neck and long sleeves.
Why do the neck, cuffs and hem look rolled?
Because they are meant to. The neckline, cuffs and hem are all finished as rolled edges instead of ribbed bands, so the knit curls softly rather than gripping. In wear that means a cuff that pushes up the forearm easily and a hem that falls over a waistband without leaving a ridge across it. The seams are left exposed on the outside as part of the look too, so the way it is put together stays visible rather than hidden inside.
