The easiest path to comfort and a smooth silhouette is a careful set of measurements and a calm fit check at home. This guide walks you through every step so you can match your numbers to the Tuckituppp size chart and start strong on day one.

What you need

A soft measuring tape, a mirror, and a note on your phone. Measure on bare skin or over very thin underwear. Stand tall, breathe normally, and keep the tape level and snug without squeezing.

Step by step measurements

1. Natural waist
   Find the narrowest part of your torso above the belly button and below the ribcage. Wrap the tape around this point. This number helps confirm overall size and comfort.
2. High hip or waistband position
   Most people prefer the waistband to sit a little below the natural waist. Wrap the tape where you expect the band to rest. This is your primary sizing measurement for tucking underwear.
3. Low hip
   Measure around the fullest part of the hips and seat. This number helps you choose a size that sits smoothly under clothing without digging or rolling.
4. Rise for comfort
   Starting at the front where the waistband will sit, guide the tape gently between the legs and up to the back where the waistband will sit. Keep the tape close to the body but not tight. This front to back distance tells you whether you will prefer a little more depth for movement and all day wear.
5. Record and compare
   Write down your four numbers and compare them to the Tuckituppp size chart. If you fall between sizes, choose the one that promises secure support without squeezing. A calm fit is always the right choice.

Fit checks at home

Start with clean dry skin. Step into your Tuckituppp underwear and settle the garment slowly. The cotton inner layer is there to be kind to skin while the outer finish gives reinforcement and the look you love. Wear the garment for at least fifteen minutes while you walk, sit, and stretch. You are looking for smooth lines, straps that lie flat, and a steady hold without pinching, tingling, or pressure. If you feel discomfort, remove the garment, rest for a moment, and reassess size or placement.

Fine tuning your choice

Different days call for different finishes. Lycra and cotton offer softness and easy movement. Glossy vinyl look and velvet bring a dressy feel while the cotton inner layer stays breathable next to the skin. If you want a little more waist stability during active days, consider styles with an elastic band or multi strap stability features. If your waistband slides or your rise feels short, you may need to adjust size or select a style with more depth.

Care that preserves fit

Gentle care helps your measurements stay true over time. Rinse promptly after a long day, wash with mild detergent, and air dry to protect fibers and stretch. Rotate between pairs so each garment can rest and recover, just like you.

When in doubt, ask

If you are unsure where you land on the chart, send your measurements and typical waistband placement to the team at Tuckituppp. Our goal is simple. A supportive fit, breathable comfort, and a foundation that lets you move through your day with ease and confidence.
