A step-by-step guide to measuring for Everybody Boxer Donkey Bamboo, reading the size chart, and getting a comfortable fit from XS to 3XL.

Quick answer

Measure your waist and hip at home, then compare those numbers to the Everybody Boxer Donkey Bamboo size chart. If you are between sizes, size up for a relaxed fit or stay true to size for a closer fit. The boxer is designed to sit comfortably on the hip, so your hip measurement often matters more than your waist.

Choosing the right size in the Everybody Boxer Donkey Bamboo comes down to two measurements and one honest look at how you like your underwear to feel. This guide walks you through measuring, reading the chart, and checking the fit so you can order once and get it right.

Bamboo boxers have a soft, flexible feel, but that does not mean sizing is guesswork. The steps below apply whether you are buying your usual size or exploring 3XL underwear sizing for the first time.

Measure your waist and hip properly

Use a soft tape measure and stand in front of a mirror so the tape stays level. Measure your natural waist, which is the narrowest part of your torso, usually just above the belly button. Keep the tape snug but not tight, and breathe normally. Then measure your hip at the fullest point, usually around the seat. Write both numbers down in centimetres or inches, whichever matches the size chart you are using.

A common mistake is measuring over thick clothing or pulling the tape tight to get a smaller number. That leads to a boxer that digs in or rides up. Measure against bare skin or thin underwear, and if you get a number that falls between two sizes, note both.

  • Checkpoint: your waist and hip measurements should be taken at the same time, with the tape parallel to the floor.

Read the Everybody Boxer size chart by hip, not just waist

The Everybody Boxer Donkey Bamboo is cut to sit on the hip, so the hip measurement is often the deciding factor. Start with your hip measurement and find the size range it falls into. Then check your waist against the same row. If your waist points to one size and your hip points to another, choose the size that matches your hip for the best everyday comfort.

For example, if your hip measures 98 cm, you would look at the medium range in a typical chart. If your waist is closer to a small, the medium still gives you room without feeling loose. The goal is a boxer that stays put without leaving marks.

  • Common mistake: ignoring hip measurement because you know your waist size. The hip is what keeps the boxer in place.

Decide between a close fit and a relaxed fit

Everybody Boxer Donkey Bamboo is designed for everyday wear, so think about how you want it to feel under your clothes. If you prefer a close, supportive fit, choose the size your hip measurement points to. If you like a looser, breezier feel, or you are between sizes, size up. Bamboo fabric has some natural stretch, but it should not be stretched to fit.

A good test is to sit, squat, and take a few steps after trying them on. The waistband should stay flat and the legs should not creep up. If you are shopping for 3XL underwear sizing, the same logic applies: start with your hip measurement and use the chart as your guide.

  • Checkpoint: if the waistband rolls or the fabric pulls across the seat, try the next size up.

Check the fit when your boxers arrive

When your Everybody Boxer Donkey Bamboo arrives, try it on over clean underwear first. Check that the waistband sits comfortably on your hip without digging in, and that the leg openings do not pinch. Move around, bend over, and sit down. The boxer should move with you, not against you.

If something feels off, compare the garment measurements to the size chart before deciding to exchange. Sometimes a different size solves the issue; sometimes you simply need to adjust how you wear them. Trust how they feel during normal movement, not just how they look standing still.

  • Next step: if the fit is close but not perfect, try washing them once according to the care label before exchanging, as bamboo may relax slightly.

Your step-by-step sizing process

  1. Measure your hip at the fullest point: Stand with feet together and run a soft tape around the fullest part of your seat, keeping it level. This is the single most important number for the Everybody Boxer Donkey Bamboo because the boxer sits on the hip. Write this number down and use it as your starting point.
  2. Measure your natural waist: Find the narrowest part of your torso, usually just above the belly button, and measure without pulling the tape tight. This confirms whether you are between sizes. If your waist and hip point to different sizes, follow your hip.
  3. Match your hip to the size chart: Find the size row where your hip measurement fits. Check that your waist also falls within the range for that size. If you are on the upper edge of a range, consider sizing up for a relaxed fit. Checkpoint: the size that matches your hip is usually the right one.
  4. Decide your preferred fit: Choose the size that matches your hip for a close fit, or size up for a looser feel. Bamboo fabric moves with you, but it should never feel tight across the seat or waist. If you are between sizes, sizing up is the safer choice for everyday comfort.
  5. Try them on and move around: When your boxers arrive, wear them for a few minutes and sit, squat, and walk. The waistband should stay flat and the legs should not ride up. If they do, exchange for a different size. Next step: if the fit is almost right, check the care label before washing, as some fabrics relax slightly after the first wash.

Product facts that help with sizing

  • Pouch Boxer Tangerine: The Pouch Boxer has a double layered pouched area providing extra room in the front. Because it is double layered it does act as a gusset, although it doesn't reach quite as far back as our flat fronted styles. If you need extra room in the front, the Pouch Boxer is a better choice than a flat front style. The double layer also adds a bit of structure, which can affect how the boxer sits on your hip.
  • Flat Front Boxer Hot Pink: The New Improved Flat Front Boxer have a double layered gusset area and a flat front. Because it is double layered it does provide some smoothing, if you need extra room in the front you might need our pouch fronted style. A flat front gives a smoother look under clothing, but it offers less front room than a pouch style. Knowing this helps you choose the right cut before you worry about size.
  • THUNDERTHONG BLACK - limited sizes: The ultimate thong in the always faithful plain black option, sits high on the hip like original Thunderpants with full front cover. Thunderthongs are sewn with soft flat narrow binding for extra comfort and less VPL. If you are comparing thong sizing to boxer sizing, note that this thong sits high on the hip. Use the same hip measurement method for a consistent fit across styles.

Getting the right size in the Everybody Boxer Donkey Bamboo starts with your hip measurement and a quick check against the chart. Measure honestly, choose based on how you like your underwear to feel, and use the steps above to avoid the guesswork. If you are still unsure, size up for comfort.
