Re-measuring for a replacement suit: using your old suit's numbers

Use your old suit to learn where the fit worked or failed, then measure your body again before you order. The store's size charts and forms ask for body measurements, not garment measurements, so numbers read off the old suit cannot go straight into them.

Step 1: write down what the old suit told you

Before you lay it out, note the size on the label and where it felt right or wrong. A good seated fit means sleeves reach the wrists and legs cover the ankles. Legs should reach the ankle bone and overlap the racing shoe by at least 1 inch (2.5 cm) when seated. Cuffs should overlap glove wrists. Too loose bunches and traps heat; too tight restricts movement and may compromise seam integrity.

Step 2: measure the old suit flat

Lay it flat, zipped, and record sleeve length, inseam and chest width across the suit. Photograph the tape on each point. Treat these as garment numbers for your own comparison, for example "the old inseam was fine" or "the sleeves were short". They are not what the store asks for, and we found no source that converts them into body measurements.

Step 3: measure your body again

Measure in your driving position, seated, wearing the base layer you plan to use, with someone else holding the tape. The store says some points need another person.

The waist point is where store pages disagree. One chart says about 5 cm (2 in) below the navel, the size chart page says 6 cm (2.4 in), and a store blog says in line with the navel. The measuring page also says to find the hip bones by feel and tie a level string around the waist at those points. Ask the store which point applies to your suit before you measure the waist.

The measuring page is the store's custom-suit form; it also lists longer sets of lengths and circumferences.

Step 4: account for body changes

If your weight, muscle or posture has changed since the last order, trust the new numbers, not the old size. If you fall between sizes, store pages differ: one says choose Custom Size, another says measure again and pick the size that lets you move freely. Ask support before deciding.

Step 5: submit and keep records

Submit your measurements after ordering, with the order number, before production. Custom Size and Custom Made orders cannot be returned or exchanged unless faulty or the store made a mistake. For standard sizes, the shipping page says 14 days and the FAQ says 30 days, so confirm in writing. See returns and exchanges for fit and contacting Joni support.
