Unisex sizes usually correspond to men's sizes in practice. Women often choose one size smaller for unisex clothing or check the CM measurements directly. Isteshaltbar states as a rule of thumb: Unisex S roughly corresponds to typical women's and men's ready-to-wear sizes in the mid-range; Unisex XS corresponds to typical smaller women's and men's sizes. The exact values can vary depending on the brand. The most reliable method for unisex size conversion: measure bust, waist, and hip circumference in centimeters, then compare with the brand's size chart. If unsure, choose the smaller unisex size and check the return policy.

  • Unisex cuts are usually based on men's measurements
  • Women: often choose -1 unisex size
  • Measurements in cm are more reliable than letter sizes
  • Always check the brand-specific size chart

What "Unisex" means in clothing and why unisex cuts fit differently

Unisex refers to garments that can be worn by all genders. The cut avoids typical gender accents: no waist tapering, no accentuated hip curves, no gender-specific shoulder lines. Typical unisex items include T-shirts, hoodies, sweatshirts, jackets, and sneakers.

The crucial difference from women's fits lies in the cut. Unisex models are straight and wider because they are designed for men's bodies. A women's T-shirt in size S has a tighter bust circumference and a narrower shoulder width than a unisex T-shirt in S. For women, this means that the same letter size will fit significantly looser in unisex.

  • Unisex cut: straight, no waist tapering, wide shoulders
  • Women's cut: tailored, narrower shoulders, accentuated hip area
  • Typical items: T-shirts, hoodies, sweatshirts, jackets, sneakers
  • Consequence for women: Unisex tends to be one size larger than usual

Conversion chart: Unisex (XS–XXL) to women's and men's (EU)

The following table shows approximate conversion values for unisex letter sizes to EU ready-to-wear sizes, as well as typical body measurements in centimeters. Deviations depending on brand and cut are normal.

Size chart for converting unisex sizes to women's and men's EU sizes

Unisex Women (EU) Men (EU) Bust (cm) Waist (cm) Hip (cm)
XS 36–38 44–46 80–88 64 88–90
S 38–40 46–48 88–96 72–78 94–98
M 40–42 48–50 96–102 80–88 100–102
L 42–44 52–54 104–110 88–96 106–110
XL 46–48 56–58 112–118 96–102 112–118
XXL 50–52 60–61 120–126 104–110 118–122

Manufacturer size charts like MASCOT's provide specific CM values for bust, waist, and hip measurements, as well as inseam and sleeve lengths. These values serve as a guide.

  • Brand charts always take precedence over this overview
  • For oversized cuts, the actual garment width may significantly exceed body measurements

How to measure yourself correctly: Bust, waist, hips, and more

Accurate body measurements are the basis of any size conversion. A tape measure and a second person to help with measuring are sufficient.

  1. Bust circumference: Place the tape measure horizontally around the widest part of the bust, letting your arms hang loosely. Read the value in cm.
  2. Waist circumference: Measure at the narrowest part of your torso, usually just above the navel. Don't pull in your stomach.
  3. Hip circumference: Measure at the widest part of your hips, about 20 cm below the waist.
  4. Inseam length: Measure from the crotch seam to the ankle, preferably in close-fitting underwear or leggings.
  5. Sleeve length: Measure from the shoulder joint to the wrist, with the arm slightly bent.

Pro Tip: Always measure in close-fitting underwear or a thin shirt, never over a thick sweater. Stretchy fabrics often give 1–2 cm after washing; for woven fabrics without stretch, it's better to lean towards the upper end of a size range.

Practical sizing tips for women, oversize cuts, and fit decisions

When it comes to unisex clothing, women face a concrete decision: letter size or measurements? The answer depends on the cut.

  • Rule of thumb for women: Choose one unisex size smaller than your usual women's size. If you normally wear women's M, opt for unisex S.
  • Bust measurement is key: For broad shoulders or a larger bust, it's better to go by CM measurements than by the rule of thumb.
  • Oversized cuts: For oversized tops from Beachbodyz, the cut is deliberately wide. Women who want a casual fit can choose their normal unisex size; those who prefer a more form-fitting look should choose -1.
  • Material influence: Jersey fabrics with elastane content stretch 3–5 cm and forgive sizing inaccuracies. Canvas or tightly woven cotton without stretch have little leeway.

Three practical cases:

  • Woman with broad shoulders (bust circumference 96 cm): Unisex M fits according to measurements, even if the women's size would be 40.
  • Man with narrow hips (hip circumference 88 cm): Unisex S is sufficient, even if men's 48 is the usual ready-to-wear size.
  • Unisex hoodie as a gift: Without measurements, it's better to choose one size larger and check the return option.

Quick cheat: Convert Unisex S/M/L to EU, UK, and US

When ordering internationally, sizing systems vary. Unisex sizing usually follows the men's scale.

  • Unisex XS: EU 44–46 (men's) / UK 34–36 / US XS
  • Unisex S: EU 46–48 (men's) / UK 36–38 / US S
  • Unisex M: EU 48–50 (men's) / UK 38–40 / US M
  • Unisex L: EU 52–54 (men's) / UK 42–44 / US L
  • Unisex XL: EU 56–58 (men's) / UK 46–48 / US XL

Important: US and UK systems differ significantly between women's and men's sizes. If you order a unisex item from a US shop, use the men's US scale. Ready-to-wear size conversion tables show the exact formulas for EU/UK/US as well as inch measurements for waistbands. For international orders, always use CM measurements as a reference, not just the letter size.

Why sizes vary between brands and how to avoid returns

Two brands, both labeled "Unisex M," can differ by 4–6 cm in bust circumference. Clear size charts with defined measurements significantly reduce returns and improve purchasing decisions.

Causes for deviations:

  • Different measuring standards: Some brands measure the finished garment, others provide body measurements.
  • Fit variations: Slim, Regular, and Oversize have different allowances on body measurements.
  • Material stretch: Fabrics with elastane content are cut tighter.
  • Manufacturing tolerances: Industrial production allows deviations of ±1–2 cm.

Checklist when ordering:

  • Compare your own CM measurements with the brand's size chart
  • Read product images and model specifications (height, size worn)
  • Check return policy and deadlines before purchase
  • If unsure, ask customer service for exact garment measurements

Pro Tip: Lay your favorite shirt flat and measure bust width and length. Compare these values directly with the manufacturer's product measurements. This is more precise than any letter size conversion.

How Beachbodyz unisex products fit and which size is right

Beachbodyz produces sustainable streetwear from GOTS-certified organic cotton and recycled polyester. The cuts are deliberately oversized.

Specific recommendations:

  • Beachbodyz Oversized T-shirts: Women tend to choose -1 unisex size. If you wear women's 38, opt for unisex XS or S.
  • Beachbodyz Hoodies (Regular Oversize): Here, the normal unisex size can be chosen based on bust circumference, as the cut already accounts for roominess.

Pro Tip: The Beachbodyz size chart on the product page contains the current garment measurements for each size. Checking there before purchasing saves you a return.

Why precise size charts are more valuable than letters

Letter sizes like S, M, or L are conventions, not norms. Two manufacturers, both printing "M," can deliver garments with a 4 cm difference in bust circumference. This is not a mistake, but a structural characteristic of the ready-to-wear market.

Those who buy exclusively by letter size buy by probability. Those who buy by CM measurements buy by facts. Beachbodyz has therefore invested in a detailed size chart: not as a marketing tool, but because returns cost resources and an incorrect fit reduces wearing comfort. Sustainability does not end with the material. It also begins with a garment fitting on the first purchase and being worn for a long time.
