Triumph Size Guide
Triumph is a leading European intimate apparel brand specialising in bras, knickers, and shapewear. The brand uses a UK-based sizing structure across its collection, making it straightforward to find your correct size with accurate measurements. Triumph bras are engineered for comfort and support across a comprehensive range of band sizes (30–50) and cup sizes (AA–K), with multiple fit options including traditional wired styles and the innovative Fit Smart range, which simplifies sizing into just five standardised sizes. Whether you're seeking everyday comfort, sports performance, or shaping support, Triumph offers designs tailored to different body types and preferences.
How to Measure
- Underbust measurement: Measure snugly around your ribcage directly under your bust, keeping the tape horizontal and parallel to the ground. This measurement determines your band size.
- Bust measurement: Measure loosely around the fullest part of your bust at nipple level, keeping the tape horizontal. Do not pull tight.
- Cup size calculation: Subtract your underbust measurement from your bust measurement. Each inch (or 2.5 cm) of difference equals one cup size: 1 inch = A cup, 2 inches = B cup, 3 inches = C cup, and so on.
- Waist measurement: Measure around your natural waistline where you naturally bend, keeping the tape comfortably loose.
- Hip measurement: With feet together, measure around the fullest part of your hips and bottom.
- Take measurements in bare skin or thin underwear for accuracy. Avoid measuring over clothes, as this will skew your results. Measure in the morning before activity, when your body is most relaxed.

Product-Specific Guidance
Wired & Underwired Bras
Triumph's traditional wired bras offer structured support and defined shaping. These styles typically feature underwires that follow your natural breast contour. Choose your size based on accurate underbust and bust measurements using the band and cup size chart above. Wired bras from Triumph are available in the full range of band sizes (30–50) and cups (A–K), giving you precise fit options. If you fall between measurements, consider that bras with smaller cups run slightly tighter in the band.
Sports Bras & triaction by Triumph
Triumph's sports bra range, including the triaction by Triumph collection, caters to high-impact activities with superior support and moisture-wicking fabrics. Sports bras are sized using the same UK band system (band sizes 70–115 in European notation, equivalent to 32–50 UK), with cup sizes ranging from A to H. For the best support during exercise, ensure your underbust measurement is accurate and consider trying a bra slightly snugger in the band than your everyday size. Sports bras prioritise stability over comfort, so a firm band is intentional.
Soft-Cup & Non-Wire Bras
Triumph offers comfortable soft-cup and non-wired styles for everyday wear, lounging, and light support. These bras still use the standard UK sizing system and deliver gentle shaping without an underwire. Soft-cup styles are ideal if you prefer a lighter feel or find underwires uncomfortable. Fit Smart sizes are frequently available in soft-cup designs, offering a simplified option for those who prefer not to calculate cup sizes.
Knickers, Briefs & Thongs
Triumph's knickers, briefs, and thongs use a separate UK size scale (6–24) based on waist measurement rather than the bra band system. Refer to the knickers size chart for the correct fit. Triumph offers a variety of brief styles from high-waisted to minimal coverage thongs, all sized by waist circumference. If between sizes, choose the larger size for all-day comfort.
Shapewear & Shaping Briefs
Triumph's shaping range helps smooth your silhouette under fitted clothing. Shaping briefs and control shorts follow the standard UK knickers sizing (6–24) and should be chosen based on your waist measurement. For maximum smoothing, select a size that feels snug but not restrictive; shaping garments work best when they stay in place without rolling or riding up.
Sizing Tips
- Measure accurately every time: Body measurements can shift due to weight changes, posture, and even time of day. Always measure yourself directly against your skin in the morning for the most reliable fit.
- Band size takes priority: A well-fitting band is more important than cup size. If your band rides up at the back or slips sideways, the band is too large. If it leaves red marks or digs in, it's too tight. The band should sit horizontally and parallel to the ground all the way around.
- Check cup fit carefully: The cup should fully contain your breast tissue with no spillage (quad-boob) or empty space. Wires should sit flat against your ribcage, not poking into breast tissue or armpits. If you spill out of a cup, size up in cup; if cups are empty, size down.
- Triumph's Fit Smart range streamlines choice: If traditional band-and-cup sizing feels overwhelming, the Fit Smart collection uses just five sizes and removes the need to calculate cup size. It's an excellent starting point for new fitters.
- International conversions are available: Triumph uses UK sizing as standard. EU sizes align with UK (e.g., UK 34 = EU 75), and sizes convert to US, Canadian, and Australian equivalents as shown in the size guide. Always verify conversions for your destination country.
- Return within the stated period if unsure: Triumph offers hassle-free returns, typically within 35 days. If a size doesn't feel right at home, use this window to exchange for a different band or cup size at no cost.
- Band size may differ between styles: Different bra designs and collections (e.g., padded, minimiser, balconette) can fit differently due to cut and fabric. Always check individual product reviews and fit feedback before ordering.
- Sister sizing offers flexibility: If your usual size is sold out, you can try a sister size (one band larger with one cup smaller, or vice versa). For example, 36D is a sister size to 38C. Sister sizing works best in wired bras with consistent underwire diameter.
