Plus Size Harley Quinn Gold Overalls Costume for Women

Your hips at 120cm are about 47 inches, which lands closest to the 2X waist of 45 inches and chest of 45.5 inches, though the 3X with a 48.5 inch chest and 48 inch waist would give more room through the hips and thighs. Since you mention big thighs and a fuller seat, the 3X could be the more comfortable fit, and the adjustable shoulder straps mean you can take them in easily for your smaller waist. Comparing your hip measurement against our size chart is the surest way to decide between the two.

The overalls feature a front zipper and antique brass tone buckles on adjustable shoulder straps, but pockets aren't part of their construction.

At 5'5" and 180 pounds in a size 16, your measurements will likely land closest to our 1X, which has a 41.5" chest, 41" waist, and a 62" jumpsuit length. Since costume sizes run differently from clothing sizes and the overalls have a front zipper rather than stretch, I'd suggest comparing your actual chest and waist measurements to those numbers before deciding, and sizing up to 2X if you're right at the edge.

The 2X overalls measure 45 1/2" at the chest and 45" at the waist, and the shoulder straps are length adjustable with metal slides, so you can dial in the fit rather than just accepting whatever the default fall is. The front zipper closure also lets you control how snug things feel through the torso. If you're only an inch off from the 2X measurements, that adjustability should help you get a fitted look rather than a swimming one.
