Finding a bra you love should be empowering. That’s why we’re here with the deets on how to do it! 

Your bra FAQs, answered!

Q: How does bra sizing work?

A: Finding your best fit is a little different for bras than it is for tees and tanks—that’s why there are two more specific measurements used to figure out your bra size:

  • Your band size (e.g., 36 or 38) is measured around your ribcage. 
  • Your cup size (e.g., B or DD) is measured around the fullest part of your chest.  

Q: How do you measure for your bra size?

A: It’s easy! Meet your newest BFF: the Best Fit Finder. The BFF is our Aerie-exclusive way to measure your bra size. Check out this video of Iskra showing you how to use it. The BFF will be back in stock at soon, or you can visit us in stores to try it out.

Q: How should your bra fit you?

A: All that matters? That it makes you feel good! Here are some tips:

  • Your bra band should feel secure and even on the middle hook.
  • The cups in your bra should hug your shape and feel supportive, without any gaps at the neckline. 
  • Straps should feel snug, comfortable and centered on your shoulders, and should never feel like they’re digging in.

Your bra FAQs, answered!

Q: How often should you wash a bra?

A: A good routine is every 1-2 weeks. And of course:

  • This depends on how many bras you have in your rotation (the more you wear it, the more you wash it).
  • The less you wash your bras, the longer they will maintain their shape.
  • To wash your bras: wash them by hand with mild detergent and cool water, and always air dry. 

Q: Should you wear a bra to bed?

A: Only if you want to! 

  • If you do, have no fear—sleeping in a bra doesn’t alter your breast shape in any way.
  • If you’re more comfortable sleeping in a bra, just make sure that it isn’t too tight.
  • Try one of our bralettes, they’re amazing for ZZZing.
Your bra FAQs, answered!

Q: How many bras should you own?

A: The more you own, the longer they’ll last! 

  • Consider having enough bras to make it to laundry day—that way your faves last longer and hold their shape and support.

Q: How often should you replace a bra?

A: It depends!

  • We think replacing a bra after about a year is good, but that depends on how it feels and what kind of shape it’s in.
  • Wear one of your faves ALL the time? Get 1 or 2 backups! Having enough bras to cover your work or school week will help them last longer.

Q: How will you know when to replace a bra?

A: If your bra has stopped making you feel supported and comfortable—ditch it!

  • Replace your bra if the band feels too loose (even on the tightest hook). 
  • If the straps are too stretched out or you see any loose threads or underwire poking through, it’s time to say goodbye.

3 ways to wear our NEW Real Me Wireless Bra

We added 3x the feel good to our Real Me bra collection! The all-new Real…


  1. Linda Qint(Sorenson)

    So, I've always had luscious boobs. Last bra sizing 38DDD. I hate underwires. I'm 68, clean and care for the elderly and sweat like a cold beer. What type of bra would you suggest? I also hate sport bras that flatten and are not sexy or pretty.

    1. Aerie

      Hi Linda! If you’re not a fan of underwire, try one of our wireless bras. If you’re shopping online, you get free shipping & free returns on bras, so try on whatever you want! You can also come see us any time in stores for a free bra fitting & tips on finding your best fit from the pros. Hope you find a bra that feels good!

  2. Megan Trenery

    Why are you discontinuing the Real Me Bralette and scallop bralette? They are the best. Super thin, comfy, and dry fast! Please make more like them or don't get rid of them!! They're the only bras I wear.

    1. Aerie

      Hi Megan! We do have some new Real Me sports bras online now, but you’re right that the style is going away. Have you tried our new Real Free bralettes? They also have an amazing soft & smooth barely-there fabric, & there are more styles coming soon.

  3. Brianna C.

    I have tried different sizes of bralettes (S&M) and i usually wear a size 32D-DD… (TMI) but my nipples fall out ! How can I fix this?!! I prefer bralettes to bras because they’re so much more comfy!

    1. Aerie

      Hi Brianna! Have you tried one of our bralettes that come in D & DD sizes? They have extra support & coverage—see if that helps! We have free shipping & free returns on bras & bralettes at so you can find your best fit.

  4. Bailey

    Why are the bralettes sizes in small, medium, large and not regular bra sizes like 32A,32B and so on? It makes buying the right size bralette difficult and hard to know if the size will fit my bra size.

    1. Aerie

      Hi Bailey! Thanks for your comment. Click the “Size Chart” button on the product page, and you’ll see the conversion from bra to bralette sizing.
