Singapore Bra Size Calculator & Converter

Measure in centimetres — Singapore retail sizing uses the international standard directly

What Is the Singapore Bra Sizing System?

Singapore is best treated as a dual-label market. Many retail size charts group Singapore with USA-style band numbers such as 30, 32, 34, 36 and 38, while some international conversion charts show Singapore beside EU-style numbers such as 70, 75, 80 and 85. Both systems are common enough that shoppers need a conversion-first calculator instead of a single-label answer.

This means a Singapore shopper buying a Sorella or Triumph Singapore 34C (UK/US-style retail standard, 68–72 cm underbust, C cup) and a Victoria’s Secret bra in the same shopping trip must navigate two completely different numbering systems. Victoria’s Secret or imported US stores sell in US sizing — the same shopper’s Victoria’s Secret size would be US 34C. The numbers look different but the fit is identical.

For shoppers, the practical rule is simple: if the product label shows 30–44, treat it like a UK/US/Singapore UK/US-style band; if it shows 65–105, treat it like EU; if it shows 80–120, treat it like FR/ES. Sorella, Wacoal SG, Sorella Singapore, Triumph SG, Uniqlo Singapore, Zalora SG and imported online listings may not always present the same label style, so conversion is part of the buying process.

How to Measure Your Singapore Bra Size

Singapore retail sizing is centimetre-based with no offsets. You need your underbust and overbust in centimetres.

1. Prepare correctly

   Wear a non-padded bra or no bra. Stand naturally with arms relaxed. Triumph Singapore, Sorella Singapore and Wacoal Singapore’s fitting guidance — available in their Wacoal SG and Sorella store fitting rooms — recommends measuring without a bra for maximum accuracy.

2. Measure your underbust in centimetres

   Wrap the tape snugly around your ribcage directly beneath your bust. Keep it parallel to the floor. Exhale fully and record to the nearest 0.5 cm. Your Singapore band size follows the Singapore retail-style band table: 68–72 cm is usually SG 34, 73–77 cm is SG 36, 78–82 cm is SG 38.

3. Measure your overbust in centimetres

   Measure around the fullest point of your bust. Keep the tape horizontal and loose enough to slide one finger underneath. Record to the nearest 0.5 cm.

4. Calculate your SG / Triumph Singapore, Sorella Singapore and Wacoal Singapore band

   Match your underbust measurement to the band table: 58–62 cm = SG 30, 63–67 cm = SG 32, 68–72 cm = SG 34, 73–77 cm = SG 36, 78–82 cm = SG 38, 83–87 cm = SG 40, 88–92 cm = SG 42. If you sit between two sizes, try the tighter band first because elastic relaxes with wear.

5. Calculate your SG cup letter

   Subtract base from overbust. As a practical calculator rule: 10–12 cm = A, 13–15 cm = B, 16–18 cm = C, 19–21 cm = D, 22–24 cm = DD/E. Triumph Singapore, Sorella Singapore and Wacoal Singapore commonly groups DD and E together on charts, so the calculator displays DD/E for that range.

Singapore US-style sizes compared with US, UK, AU, FR and ES systems

Singapore Cup to US, UK, AU Conversion

SG US-style cups are identical to EU, Spanish, Italian, and German cups. Above D cup, SG letters run one step ahead of UK/AU — SG DD/E = UK DD (not UK E). For US conversion above D: SG DD/E = US DD, SG DDD/F = US DDD.

What Are Sister Sizes in Singapore Bras?

Sister sizes in the SG US-style system work identically to Spain and Italy — bands step in 5 cm, cups shift by one letter.

Singapore Bra Brand Sizing Differences

Singapore’s dual-system market means every major brand must be evaluated on which sizing convention it uses — EU or US.

Signs Your Singapore Bra Size Is Wrong

Band size problems

• Band rides up at the back: band too big. Try one band down, one cup up (SG 36B → 75C).
• Band digs in or leaves marks: band too small. Try one band up, one cup down (SG 34C → 80B).
• Band pulls forward when arms raised: band too loose. Tighten hooks or size down 5 cm.

Cup size problems

• Spillover at top or sides: cup too small. Size up one SG cup (SG 36D → 80E).
• Gaping or wrinkling: cup too big. Size down one (SG 36D → 80C).
• Underwire on breast tissue: cup too small. Size up immediately.
• Centre gore not flat against sternum: cup too small or wire too wide for breast spacing.

Shopping International Brands as a Singapore Shopper

Buying from US retailers (Victoria’s Secret US, Amazon US)

SG band to US band: SG 34 = US 34, SG 36 = US 36, SG 38 = US 38. Cup through D: identical. Above D: SG DD/E = US DD, SG DDD/F = US DDD, SG G = US DDDD. So SG 34DD/E = US 34DD. This is identical to buying from Victoria’s Secret or imported US stores — same US sizing throughout.

Buying from Spanish retailers (El Corte Inglés, Selmark ES)

SG/US-style and ES labels are not written the same. SG 34DD/E usually maps to ES 75E. Convert your SG/US-style band to the EU/ES label before buying from Spanish retailers. SG 34C usually maps to EU/ES 75C.

Buying from UK retailers (Bravissimo, ASOS UK)

SG band to UK band: SG 32 = UK 32, SG 34 = UK 34, SG 36 = UK 36. Cup through D: identical. Above D: SG DD/E = UK DD, SG DDD/F = UK E, SG G = UK F. So SG 36DDD/F = UK 36E. Drop one cup letter above D.

Buying from French brands (Chantelle, in Singapore online stores)

FR band = SG band + 15: SG 34 → FR 90. SG 36 → FR 95. Cup letters identical — SG DD/E = FR E. Chantelle FR 90E sold in Singapore online stores = Triumph Singapore, Sorella Singapore and Wacoal Singapore SG 34DD/E. Add 15 to your SG band and keep the same cup letter.

Singapore Bra Size Terms: Talle, Copa, Contorno and Busto

In Singapore, the words used on product pages and in stores matter. A shopper may search for talla de sostén, talla de sostén, tabla de talles de sosténs, copa de sostén, base bajo el overbust, or simply qué talla de sostén soy. These terms often point to the same fitting problem: the buyer knows her measurements, but the label on the product page does not clearly explain whether the number is local, EU, FR-style, or imported US sizing.

This is why the Singapore calculator does not stop at one result. It gives the local label, the EU conversion, the US/UK equivalent, the AU dress-size band, the French/Spanish label, and the Italian conversion. That structure is useful for shoppers comparing Singapore retailers, Sorella Singapore, Wacoal Singapore, Triumph SG, Uniqlo Singapore, Marks & Spencer Singapore and Zalora SG and MercadoLibre listings, imported American bras, and European brands listed through multi-brand retailers.

Singapore Size Examples

Here are common examples that help users understand what the calculator is doing:

Common Fit Problems for Singapore Shoppers

Many Singapore shoppers buy by the old label they have worn for years. The problem is that band elasticity, cup depth, and imported sizing can change the fit even when the label looks familiar. If your old 95B feels loose in the back and small in the cup, the better starting point may be 90C or 90D. If your 90C feels tight in the band but the cups are correct, try 95B as a sister size. The calculator shows those sister sizes automatically.

• Back band rides up: the band is too loose. Try one US-style band smaller and one cup larger.
• Breast tissue spills over the cup: cup is too small. Keep the band and size up in cup.
• Center gore floats: cup is too small, wire shape is wrong, or the bra is too shallow.
• Straps carry all the weight: band is too loose. A supportive bra should lift mostly from the band.
• Wrinkling or empty space: cup may be too large, too tall, or the shape may not match your bust.

How to Shop on Singapore online stores

Marketplace listings are the most confusing because different sellers use different systems. A US-style brand may list 90C, a European-style product may list 75C, and an imported US product may list 34C. Before ordering, check the product size chart, the brand origin, and the available return policy. If the listing has only numbers and no cup letters, it may be a simplified fashion-size bra rather than a true band-and-cup bra.

For SEO and user trust, this page should keep repeating the decision rule clearly: 85–120 usually means Singapore/local or FR-style; 65–105 usually means EU; 28–46 usually means US/UK. That single rule helps users avoid the biggest mistake when buying online.

Singapore Bra Sizing: What Makes It Different?

Singapore is a conversion-sensitive market because stores may show either inch-style bands such as 32, 34, 36 and 38, or EU/Singapore chart bands such as 70, 75, 80 and 85. Both can describe the same ribcage measurement. For example, a shopper who wears 34C in one Singapore store may see 75C on an international Triumph-style chart. This calculator shows the local UK/US-style result first, then gives EU, FR/ES, AU and UK conversions so shoppers can move between Sorella, Wacoal and Triumph SG, Wacoal SG, Zalora SG, Triumph, Bras N Things and international online stores without guessing.

The most important rule is to look at the band number. If the label says 30, 32, 34, 36, 38 or 40, treat it like a UK/US/Singapore UK/US-style band. If the label says 65, 70, 75, 80, 85 or 90, treat it like an EU/Singapore chart band. Cup letters usually match through D, but above D the notation can change: UK uses DD, E, F and FF; US often uses DD, DDD/F and G; EU uses E, F, G and H. That is why the calculator includes all systems in one result card.
