Aerie Bra Size Chart: Find Your Best Fit Across 45 Sizes
The Aerie bra size chart currently tops out at 45 published sizes, 30A to 42DD, with G and H reserved for select styles.
Pick your size in the spectrum on the right and I’ll show you where it sits — core range, select-style, or outside what Aerie currently offers.
* G/H are select-style sizes. Every node is keyboard-operable; the HTML matrix below carries the same 45-size data for screen readers and crawlers.
Aerie Bra Size Chart Quick Answer: Range and Style Availability
The Aerie bra size chart currently lists bras in up to 45 sizes, from 30A to 42DD, with G and H cups in select styles only.
Bralettes run separately, from XXS to XXL, with D/DD cup-specific versions in select designs.
Here’s the part shoppers miss: a size existing in Aerie’s overall size architecture doesn’t mean it’s offered in every Sunnie, SMOOTHEZ, Superchill, strapless or unlined style.
Find your position in the spectrum, then confirm availability on the live product page for the exact bra you want.
Source integrity: official Aerie first
This Aerie bra size chart reorganizes Aerie’s own published sizing into an interactive format. It does not invent missing brand measurements or claim a size is stocked in every product.
The official chart, current sizing overview, live size landing pages and product selectors take priority over any interpretation added here.
Use the Aerie Bra Size Chart Finder
Use this Aerie bra size chart finder to choose the band and cup you want to check. We’ll highlight your selection in both the spectrum and the complete matrix.
The result then shows whether the size sits in the published core range, the G/H select-style zone, or outside Aerie’s current architecture.
Why 28, 44 and I are options here: they’re deliberate boundary checks. Selecting one shows clearly that it sits outside Aerie’s current range rather than silently disappearing.

Aerie Bra Size Chart: Complete 45-Size Matrix
This Aerie bra size chart maps the same 45 size positions as the spectrum above in a crawlable table.
Every live cell is clickable and keyboard-operable. G/H stay visually separate because Aerie itself calls those cups select-style sizes.

Beyond the Aerie Bra Size Chart: Bralettes and Swim
The Aerie bra size chart applies to band/cup bras, while Aerie treats bralettes and swim as separate size paths. That matters because an alpha-size bralette is not a literal bra-size conversion.
Aerie says bralettes are offered from XXS to XXL, with D and DD cup-specific options in select styles.
- Use the live product size details for the specific bralette.
- Don’t assume every S or M maps to one fixed band/cup.
- D/DD variants matter when the base alpha size lacks cup depth.
Aerie’s current size overview lists bikini tops in alpha sizes and selected band/cup sizing up to 38DD.
- Swim can use a different size path from your everyday bra.
- Check whether the bikini is alpha-sized or bra-sized.
- Band/cup swim sizing stops earlier than the published bra range.
Aerie’s range page lists one-piece swimsuits in XXS to XXL, with some styles available in multiple lengths.
- Torso length becomes a fit variable.
- A bra size alone can’t choose a one-piece size.
- Use the garment chart rather than converting from bra size.
Aerie Bra Size Chart vs Style Construction
The Aerie bra size chart is the starting point, but style construction is the second half of fit.
Aerie sells unlined, lightly lined, push-up, wireless, strapless and sports bras. The same label can feel different as cup height, wire shape, padding, stretch and support change.
Less foam can expose the real cup shape and may work differently from a molded T-shirt bra.
Natural shaping with more structure; cup height and wire width still matter.
Can feel easier through the center and ribs, but band stability remains important.
Padding changes usable cup space, so overflow or gaping can appear even in a familiar label.
Band contact matters more because the straps can’t help stabilize the frame.
Aerie Bra Size Chart Fit Troubleshooting
After using the Aerie bra size chart, change one fit variable at a time.
The advice below is Bra-Calculator.com interpretation, not an Aerie measurement formula, so keep the bra style constant while you test the band or cup.
Keep Similar Cup Capacity While Testing a Different Band
This is Bra-Calculator.com fit guidance, not an Aerie conversion chart. Use it to create a controlled comparison in the same bra style.
Availability note: sister sizes can fall outside Aerie’s published range. Each result is checked against the Aerie matrix above.
Sister sizing preserves only approximate cup capacity — wire width, strap placement and frame geometry still change.
The band is likely too loose. Try the next smaller band with a larger sister cup if available.
Example: 36C → 34DCheck the band backwards first. If it’s still too tight without the cups involved, test the next larger band and smaller sister cup.
Example: 34D → 36CKeep the band and move up a cup in the same style before changing both variables at once.
Example: 34C → 34DDon’t assume the volume is wrong. Compare a lower or more flexible cup construction before sizing down.
Try: demi / unlined / softer edgeAerie labels these as select-style cups, so switch style before assuming your size is unavailable from the brand entirely.
Try: full coverage / current live filterDon’t force a distant sister size just to stay in one brand. Use a retailer or brand that actually carries your band/cup.

How This Aerie Bra Size Chart Was Built
This Aerie bra size chart was built for source fidelity while making the official range easier to use than a static retailer table.
What comes from Aerie
- The current top-level range statement: up to 45 bra sizes, from 30A to 42DD.
- The qualifier that G and H cups are offered in select styles.
- The bralette range of XXS to XXL with D/DD variants in select styles.
- The swim range summary, including band/cup bikini sizing through 38DD.
- Live size landing pages used to cross-check active band/cup labels.
- Current product descriptions used only for style-specific fit context.
What we do not invent
- Body-measurement cutoffs the official dynamic chart didn’t expose to our crawl.
- A fixed bralette-to-band/cup conversion Aerie doesn’t publish on its accessible source.
- Guaranteed inventory for every color, collection or style.
- A claim that all Aerie constructions fit identically.
- International equivalents presented as if Aerie published them.

Aerie Bra Size Chart FAQs
What bra sizes does Aerie carry?
The Aerie bra size chart on this page reflects Aerie’s current overview: up to 45 sizes from 30A to 42DD, with G and H cups in select styles.
Exact combinations and stock depend on the bra.
Does Aerie carry 32AA?
Yes. Aerie currently has a live 32AA bra size landing page and products listed in that size.
Does Aerie carry G and H cups?
Yes, but Aerie describes G and H as select-style cup sizes. That’s why this page marks them separately in the matrix.
Does Aerie carry DDD?
Yes. Current Aerie product and size landing pages show DDD sizing, including live 32DDD, 36DDD and 38DDD pages/products.
What sizes do Aerie bralettes come in?
Aerie’s current range summary says XXS through XXL, with D and DD cup-specific sizes in select styles. Check the current product’s Size Details for the exact alpha-to-bra-size mapping rather than assuming.
Are Aerie bra and bralette sizes the same?
No. A band/cup bra size and an alpha bralette size are different labeling systems. Aerie also offers cup-specific D/DD bralette variants in some styles.
Do all Aerie bras fit the same?
No. Unlined, lightly lined, wireless, push-up and strapless bras use different construction. A current Sunnie strapless page even notes that some shoppers may want to size up a band or cup.
What if my usual size isn’t offered in the Aerie style I want?
First check another Aerie style, especially if you wear G or H, since those cups are selectively available.
If your band/cup is outside the brand’s range, don’t force a distant sister size just to stay with Aerie.
Reviewed by Amelia
A brand chart should answer two separate questions: does the brand make my size, and does this specific bra fit my shape?
Start with the Aerie bra size chart above for the first question. Then use band stability, cup contact and the construction of the exact Sunnie, SMOOTHEZ, Superchill or other style for the second.
