Question 1

Do bra sizes vary between brands?

Accepted Answer

Yes, bra sizes can vary significantly between brands. Some brands run small (Victoria's Secret, Natori), others run large or stretchy (Freya bands, Target), and some are true to size (ThirdLove, Wacoal). A 34C at Victoria's Secret may fit very differently than a 34C at Panache or ThirdLove. Cup shapes, band stretch, and measuring methods all differ between manufacturers.

Question 2

Why is my bra size different at every store?

Accepted Answer

Your bra size changes between stores due to: different measuring methods (some brands add inches, others don't), different size standards (US vs UK vs EU), varying cup shapes and depths, different band stretch and firmness, and each brand's target market philosophy. A brand targeting younger customers may size differently than one for mature women. Always try on or check return policies when trying new brands.

Question 3

Does Victoria's Secret run small or large?

Accepted Answer

Victoria's Secret bras tend to run small, particularly in the band. VS is known for using the "+4 method" which adds inches to band measurements, often resulting in customers wearing a larger band and smaller cup than they actually need. Their size range is also limited (32-40 bands, up to DDD cups), so many women find they need a different size at VS compared to other brands. If your VS bra feels tight in the band, you may actually need a smaller band and larger cup elsewhere.

Question 4

Is Victoria's Secret bra sizing accurate?

Accepted Answer

Victoria's Secret sizing is considered less accurate than many competitors. They use an outdated "+4" measuring method that often puts women in the wrong size. Many women fitted at VS discover they've been wearing a band too large and cup too small. If you've only ever been fitted at VS, consider getting measured elsewhere or using a modern bra calculator. You may be surprised by your true size.

Question 5

What is ThirdLove half cup sizing?

Accepted Answer

ThirdLove offers half cup sizes (like B½, C½, D½) for women who fall between standard cup sizes. Research shows about 50% of women are between cup sizes. If a B cup is too small and a C cup gaps, a B½ provides the perfect in-between fit. This is unique to ThirdLove and helps achieve more precise sizing. Their Fit Finder quiz can help determine if you need a half size.

Question 6

Is ThirdLove true to size?

Accepted Answer

Yes, ThirdLove is generally considered true to size. They use modern measuring techniques and offer an extensive size range (30-48 bands, AA-I cups) including their unique half cup sizes. Their online Fit Finder quiz helps ensure accurate sizing. Many women find their ThirdLove size matches their "true" measured size, unlike brands that use outdated measuring methods.

Question 7

Which bra brands run small vs large?

Accepted Answer

Brands that run SMALL: Victoria's Secret, Natori, Simone Pérèle, Calvin Klein, Savage X Fenty. Brands that are TRUE TO SIZE: ThirdLove, Wacoal, Aerie, Chantelle, Elomi. Brands with STRETCHY/LARGE bands: Freya, some Target brands. Brands with FIRM bands (may want to size up): Panache, Curvy Kate. Always check brand-specific reviews and size charts for the most accurate fit.

Question 8

What brands have the best bra size range?

Accepted Answer

UK brands offer the widest size ranges: Elomi (32-48 bands, up to UK O cup), Panache (28-40 bands, up to UK K cup), Goddess (34-48 bands, up to N cup), Curvy Kate (28-44 bands, D-K cups), and Bravissimo (28-40 bands, D-L cups). US brands with good ranges include ThirdLove (30-48 bands, AA-I cups), Lane Bryant/Cacique (34-50 bands, B-K cups), and Torrid (36-50 bands). For small bands (28-30), UK brands are your best option.

Question 9

What is the difference between US and UK bra sizes?

Accepted Answer

US and UK band sizes are identical (32, 34, 36, etc.). Cup sizes are the same through D, then differ: US DD = UK DD, US DDD/F = UK E, US G = UK F, US H = UK FF, US I = UK G, US J = UK GG, US K = UK H. UK brands use double letters (FF, GG, HH, JJ) while US typically doesn't. When shopping UK brands like Panache or Freya, make sure to convert your cup size.

Question 10

How do I convert US bra size to UK?

Accepted Answer

Band sizes are the same in US and UK (32, 34, 36). For cups: A-D are identical. After D: US DD = UK DD, US DDD = UK E, US G = UK F, US H = UK FF, US I = UK G, US J = UK GG, US K = UK H. Example: US 34DDD = UK 34E. UK brands like Panache, Freya, Curvy Kate, and Elomi all use UK sizing, so always convert before ordering.

Question 11

How does Savage X Fenty sizing compare to Victoria's Secret?

Accepted Answer

Both Savage X Fenty and Victoria's Secret run slightly small, but Savage X offers a much wider size range (30-46 bands, A-H cups vs VS's 32-40 bands, A-DDD). Savage X is known for trendier, more inclusive styles. If your VS size fits well, you may need the same or one size up at Savage X. Savage X also tends to have more stretch in their bands.

Question 12

What is the best bra brand for large breasts?

Accepted Answer

For D+ cups, UK brands excel: Panache offers excellent support with firm bands and projected cups. Elomi specializes in plus sizes with exceptional support. Freya has stylish options for full busts. Curvy Kate focuses exclusively on D-K cups. For US brands, ThirdLove goes up to I cup, and Lane Bryant/Cacique specializes in plus sizes. These brands are designed specifically for larger busts, unlike mainstream brands that simply scale up smaller sizes.

Question 13

What is the best bra brand for small breasts?

Accepted Answer

For A-B cups, great options include: ThirdLove (offers AA and half cups), Aerie (affordable with cute styles), Natori (beautiful designs, though runs small), The Little Bra Company (specializes in petite sizes), and Lively. Bralettes from Cosabella and Free People are also excellent for smaller busts. Look for brands that offer 30 and 32 bands, as many small-busted women also have smaller ribcages.

Question 14

How often should I get measured for a bra?

Accepted Answer

You should measure your bra size every 6-12 months, or after any significant body changes: weight fluctuation (gain or loss of 10+ pounds), pregnancy and postpartum, starting or stopping hormonal birth control, menopause, or if your current bras become uncomfortable. The average woman changes bra sizes 6 times in her life. Regular measuring ensures you're always in the right size.

Question 15

Why do 80% of women wear the wrong bra size?

Accepted Answer

Studies suggest 70-85% of women wear incorrectly fitted bras due to: outdated measuring methods still used by many stores, lack of size standardization between brands, wearing the same size for years without re-measuring, limited size availability pushing women into wrong sizes, and not knowing the signs of a poor fit. The most common mistake is wearing a band too large and cup too small. Getting properly fitted can be life-changing for comfort and appearance.

Question 16

What are sister sizes in bras?

Accepted Answer

Sister sizes are bra sizes with the same cup volume but different band and cup letter combinations. When you go down a band size, go up a cup letter (34C → 32D). When you go up a band size, go down a cup letter (34C → 36B). Sister sizes help when: your exact size is unavailable, a brand runs small or large, or you're between sizes. The cup volume stays the same, but the band fit changes.
