Work from temperature. The tee is the only one that works alone in real heat and the only one that layers cleanly underneath. The sweatshirt covers cool but not cold. The hoodie is the heaviest and the only one with a built-in second layer.

No. A hoodie carries noticeably more room through the body and shoulders than a tee in the same letter size, because it is cut to fit over something. Compare against a piece you own in the same style, not a different one.

A crew-neck sweatshirt, because the print area stays flat and unbroken. Hoodies have a hood seam and a pocket interrupting the panel, so they suit chest-height artwork better than full-front designs.

These carry panel prints — artwork on the front or back with the rest left plain. All Over Print runs the design across the entire garment including sleeves and seams. Panel pieces still read well when partly covered; all-over pieces need to be seen whole.

The same size usually works, and a size down usually does not. Each layer should be roomier than the one beneath it, so a hoodie bought to match your tee size will sit correctly over that tee.

Cold wash, inside out, hang dry. Heat plus tumbling is the exact combination that cracks ink, so the dryer causes more damage than the wash ever will. Never iron directly onto the printed panel.

Often yes. Check Home & Living for the same artwork on pieces with no fit involved, or a Hat if it needs to be worn. Both remove the sizing risk when buying for someone else.
