Argentina Bra Size Calculator & Converter

Measure in centimetres — Argentina local sizing uses the international standard directly

What Is the Argentina Bra Sizing System?

Argentina’s lingerie market is split between two coexisting sizing systems, which creates more complexity than any other country in the cluster. Domestic Argentina brands and European brands sold in Argentina follow the EU centimetre standard — the same system used in Spain, Italy, Germany, and the rest of continental Europe. US brands operating in Argentina, however, retain their American sizing — inch-based band numbers, US cup letters with DD and DDD notation.

This means a Argentina shopper buying a Peter Pan 75C (EU 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 Argentina sells in US sizing — the same shopper’s Victoria’s Secret size would be US 34C. The numbers look different but the fit is identical.

Peter Pan, founded in Argentina City in 1965, is Argentina’s largest domestic lingerie brand and the country’s reference for EU-standard sizing. Their sizing follows the EU standard precisely and is stocked in Sweet Victorian, Mercado Libre, and Selú across Argentina. Intimissimi, the Italian brand with stores across Argentina City and Córdoba, also uses EU sizing, reinforcing the EU standard as the dominant convention for domestic and European-brand Argentina retail.

How to Measure Your Argentina Bra Size

Argentina local 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. Peter Pan’s fitting guidance — available in their Sweet Victorian and Mercado Libre 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 Argentina band size is your underbust rounded to the nearest 5 cm: 74 cm → AR 75, 78 cm → AR 80.

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 AR band

   Round underbust to nearest 5 cm: 63–67 cm = AR 65, 68–72 cm = AR 70, 73–77 cm = AR 75, 78–82 cm = AR 80, 83–87 cm = AR 85, 88–92 cm = AR 90, 93–97 cm = AR 95. If exactly on a boundary, try the smaller band first.

5. Calculate your AR cup letter

   Subtract underbust from overbust in cm, using 2 cm intervals: 10–11 cm = A, 12–13 cm = B, 14–15 cm = C, 16–17 cm = D, 18–19 cm = E, 20–21 cm = F, 22–23 cm = G, 24–25 cm = H. AR E equals UK DD — not UK E.

This chart is the standard AR/local sizing reference used by Peter Pan, Sweet Victorian, Selú, Mercado Libre, Triumph Argentina, and all EU-standard brands operating in Argentina.

Argentina local sizes compared with US, UK, AU, FR and ES systems

Argentina Cup to US, UK, AU Conversion

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

What Are Sister Sizes in Argentina Bras?

Sister sizes in the AR local system work identically to Spain and Italy — bands step in 5 cm, cups shift by one letter.

Argentina’s lingerie market spans domestic EU-standard brands (Peter Pan) to US brands (Victoria’s Secret) — both sold in Mercado Libre and Sweet Victorian

Argentina Bra Brand Sizing Differences

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

Signs Your Argentina Bra Size Is Wrong

Band size problems

• Band rides up at the back: band too big. Try AR 5 cm down, one cup up (AR 80B → 75C).
• Band digs in or leaves marks: band too small. Try AR 5 cm up, one cup down (AR 90C / EU 75C → 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 AR cup (AR 80D → 80E).
• Gaping or wrinkling: cup too big. Size down one (AR 80D → 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 Argentina Shopper

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

AR band to US band: AR 75 = US 34, AR 80 = US 36, AR 85 = US 38. Cup through D: identical. Above D: AR E = US DD, AR F = US DDD, AR G = US DDDD. So AR 90E / EU 75E = US 34DD. This is identical to buying from Victoria’s Secret Argentina — same US sizing throughout.

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

AR and ES sizing are identical. AR 90E / EU 75E = ES 75E. No conversion needed — shop in your exact AR size from any Spanish/Argentine retailer. Selmark.es ships internationally to Argentina.

Buying from UK retailers (Bravissimo, ASOS UK)

AR band to UK band: AR 70 = UK 32, AR 75 = UK 34, AR 80 = UK 36. Cup through D: identical. Above D: AR E = UK DD, AR F = UK E, AR G = UK F. So AR 95F / EU 80F = UK 36E. Drop one cup letter above D.

Buying from French brands (Chantelle, in Mercado Libre AR)

FR band = AR band + 15: AR 75 → FR 90. AR 80 → FR 95. Cup letters identical — AR E = FR E. Chantelle FR 90E sold in Mercado Libre Argentina = Peter Pan AR 90E / EU 75E. Add 15 to your AR band and keep the same cup letter.

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

In Argentina, the words used on product pages and in stores matter. A shopper may search for talle de corpiño, talle de brasier, tabla de talles de corpiños, copa de corpiño, contorno bajo busto, or simply qué talle de corpiño 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 Argentina calculator does not stop at one result. It gives the local label, the EU base, the US/UK equivalent, the AU dress-size band, the French/Spanish label, and the Italian conversion. That structure is useful for shoppers comparing Peter Pan, Sweet Victorian, Selú, Cocot, Triumph Argentina, Mercado Libre listings, imported American bras, and European brands listed through multi-brand retailers.

Argentina Size Examples

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

Common Fit Problems for Argentina Shoppers

Many Argentina 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 local 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 Mercado Libre Argentina

Marketplace listings are the most confusing because different sellers use different systems. A local 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 Argentina/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.
