Green Monster Headpiece and Bolts Halloween Costume Accessory Prop

Costume sizes vary by brand, so each product page has its own size chart. Use this guide to take your measurements, then compare them with the chart on the product you want.

How sizes work

• Adults: Choose your size by your measurements, not by the size you usually wear.
• Kids: Kids' sizes go by age and height. Measure your child's height and check both age and height against the product's size chart.
• Between sizes: If you plan to wear the costume over clothes, choose the larger size.

Before you measure

• Use a soft measuring tape.
• Measure over light clothing.
• Keep the tape snug but not tight, and level all the way around.
• Ask someone to help if you can. It is easier and more accurate.

How to measure

Chest

Wrap the tape around the fullest part of your chest, under your arms and across your shoulder blades. Keep your arms relaxed at your sides.

Waist

Measure around your natural waist. This is the narrowest part of your torso, usually just above your belly button.

Hips

Stand with your feet together. Measure around the fullest part of your hips and seat.

Height

Stand straight against a wall with no shoes on. Mark the wall level with the top of your head. Measure from the floor to the mark.

Inseam

Measure from the top of your inner thigh down the inside of your leg to your ankle. You can also measure the inseam of a pair of pants that fit you well.

Head

Wrap the tape around your head just above your eyebrows and ears, where a hat or wig would sit. Use this for masks, wigs and hats.
