How to Measure Jackets
Lay out the jacket on the flat. Button up. Place the measuring tape beneath the armpits, around the widest part of the chest.
Measure across the narrowest part of the jacket, from one edge to the other. Make sure to keep the tape horizontally.
Lay the jacket upside-down. Place the end of the measuring tape at the top of one shoulder seam. Bring the tape straight across the top of the jacket until it meets the top of the second shoulder seam.
Turn up the collar. Place the tape end under the collar, measure from the neck seam to the bottom of the jacket.
Measure the length from the shoulder point, the top of the shoulder, to the end of the sleeve.
How to Measure Trousers
Before we start with the measuring, button up the trousers, lay out nicely on flat and smooth out any wrinkles.
Place the measuring tape across the waistband and measure the narrowest part.
Measure across the hip area, the widest part of the trousers.
Measure this part by starting from the top of the waistband to the crotch seam spot.
Lay out and fold the trousers in half. Fold the top leg up over the waistband, making the bottom of the crotch visible. Spread out and flatten the bottom trouser leg across the thigh. Measure straight across the width of the leg, below the lowest part of the crotch, perpendicular to the inseam.
Measure across the bottom of the trouser hem, from one edge of the leg opening to the other.
Lay the trousers flat on their sides, so that the legs are folded along the front and back creases. Measure from the top of the waistband down to the bottom of the leg opening, following along the side seam of the leg.
Fold up the top trouser leg. Measure from the crotch, at the spot where the front and back seams meet, down the inside of the leg to the bottom of the leg opening.
