Product Details

If you've ever felt like your bust arrives before you do, this minimizer bra gives you a smoother, more balanced line under everything you wear. It reduces the appearance of your bust by up to 2 inches, so buttons stay put and tops fit the way you pictured them. Most competitors stop at 1 to 1.5 inches, so you're getting more room to breathe here.


  • Up to 2-inch reduction: It trims the look of your bust by up to 2 inches for a proportioned silhouette.

  • Unlined smooth cups: The unlined minimizer bra shapes you without adding bulk or padding.

  • Full coverage: Fuller cups hold and contain more of your bust, so there's no spillage over the top or sides.

  • Underwire support: The wire lifts and steadies your bust for support that holds all day and into the night.

  • Smooth Nylon/Spandex fabric: Soft, stretchy fabric lies flat under clothes and moves with you.

  • Adjustable straps: Dial in the fit at your shoulders so straps stay comfortable all day.

  • Everyday comfort: Built for real 24/7 wear, so you can keep it on from your first meeting to your last errand.


How does it work? Instead of flattening you, an underwire minimizer bra redistributes and reshapes your breast tissue across your frame for a smoother, more even silhouette. That's why it's a good fit if you have a fuller or heavier bust and want a cleaner line, and yes, you can wear it every day. 


Wear it under tees, blouses, and sweaters when you want a smooth, tailored look. Prefer to skip the wire? The line also includes a Smooth Wireless Minimizer Bra.

Bra Size Calculator & Chart

Thirdlove offers over 60 bra sizes from 32 to 44 band and bra cup sizes from AA to H cup, including our exclusive half cup sizes. Using your current bra size as a starting point, you can refer to the bra cup size chart below to refine your fit.

Bra Size Calculator & Chart

How To Use The Bra Size Chart

When using the chart to find your bra size, keep in mind:

  • The band size increases as you move from left to right. Move left or right within the row if your band doesn't fit.
  • The cup size increases as you move from top to bottom on the chart. Move up or down the columns if your cups don't fit. In between cup sizes? Go up or down a half-cup! And keep in mind if you want styles that are full coverage or not!
  • Bra sizes that share a row are sister sizes, meaning they share the same cup volume (though they have different cup letters). For example, at a glance they’re all just different bra sizes. However, the row with bra sizes 36C, 38B, and 40A have something in common: they all have the same cup volume but have different band sizes. The same goes for the row with bra sizes 38H, 40G, 42F, 44E, 46D, and 48C.
Bra Size Calculator & Chart

Measure snugly around your rib cage (underbust) and around the fullest part of your bust, in inches. Step 1 gives your band. For step 2, subtract your underbust from your bust and find the difference in your band's column. These are the sizes our Bra Size Calculator gives.

Step 1: Band size by underbust measurement (inches). Each range excludes its lower value and includes its upper value.
Underbust (in) Band size
24.9 – 28.5 30
28.5 – 30.5 32
30.5 – 32.5 34
32.5 – 34.5 36
34.5 – 36.5 38
36.5 – 38.5 40
38.5 – 40.5 42
40.5 – 42.5 44
Step 2: Bra size by band and by bust minus underbust (inches). Each range excludes its lower value and includes its upper value.
Bust − underbust (in) Band 30 Band 32 Band 34 Band 36 Band 38 Band 40 Band 42 Band 44

* Also the result when the difference is exactly 2.5 in: 30B, 32A, 34AA; 4 in: 36A; 5 in: 38A; 7 in: 40B; 8 in: 42B; 9 in: 44B.

The calculator only gives a size for an underbust over 24.9 in, up to 42.5 in, with a difference of up to 13 in. Blank cells and measurements outside these ranges have no size in the calculator.

    This is my first Thirdlove

    This is my first Thirdlove bra and I am impressed. I always prefer minimizer bras and this one is comfortable, no scratchy points, and really brings you in on the sides. The fabric is smooth and the back hooks are padded- wow! I just really love this bra. I also appreciate that they offer a B cup, which normally isn't "large", but it is when your rib cage and width are wide. I usually wear a 42B, but in this bra I found I needed a 40C, but I do have a little extra weight on me right now.

    Very comfortable

    I purchased this in black and beige and I am so happy with my purchases. This bra is very comfortable and does what it says - I am very busty and this bra fits like a glove. It reduces nicely without the girls looking squashed and the straps don't cut into my shoulders and the back fits well too.

    Doesn’t last

    This is the first bra I’ve owned that actually fits me. I wear it daily. Unfortunately, they just don’t last. I had my first one replaced in less than a year. Second one is falling apart again at 8 months since my replacement. It’s a bummer because they fit so well, but I can’t justify this spend on something that continues to fall apart :(

    This bra fit perfectly when

    This bra fit perfectly when I used the tightest clasp. I contacted the personal fit people who helped me. They suggested a 34F instead and it fits a little tight but no spillage and I use the loosest clasp. I think the spandex will relax over time making this bra the perfect fit. I wear it during the day, but usually need to take it off in the evening when I'm sitting on the couch. You know the feeling. It doesn't HURT, but it's not super comfy on the rib cage when I'm sitting. For size, I measure 32.5" in the band and 38" in the breast and 34F fits snug in the band, while 36E fit a bit loose.

    I love this bra

    My breasts have changed so much since having a child and breast feeding. I tried so many styles and brands and nothing provided support or shaping, until I found this bra. It’s full coverage and the minimizing is obvious but not tight or restrictive. It gives a nice shape and cannot be seen under tops. I’m going to buy 10 more!!!!

FAQs

How much does a minimizer bra reduce?

This one reduces the appearance of your bust by up to 2 inches, while many competitors only claim 1 to 1.5 inches. That extra reduction gives you a smoother line under fitted tops and easier-closing button-downs. Results vary by your size and shape, so the Fit Quiz can help you set expectations.

How does a minimizer bra work?

It redistributes and reshapes your breast tissue more evenly across your frame instead of flattening or compressing you. The full-coverage cups and underwire contain and steady your bust so the overall projection looks reduced. You get a smoother silhouette without losing support or comfort.

Is an unlined bra the same as a minimizer bra?

Not necessarily. Unlined means there's no padding or foam in the cups, while minimizing describes how the bra reshapes your bust to look smaller. This style is both: an unlined minimizer bra that shapes you without adding bulk.

Can I wear a minimizer bra every day?

Yes. This is part of the 24/7® Classic line, built for morning-to-night wear with smooth fabric and adjustable straps that stay comfortable. The unlined cups lie flat under tees, blouses, and sweaters, so it works for both workdays and weekends.

Who should wear a minimizer bra?

It's designed for you if you have a fuller or heavier bust and want a smoother, more proportioned line under clothes. Full-coverage cups help prevent spillage, and the underwire adds lift and support. It comes in bands 30–48 and cups AA–I, including half-cup sizes.

Does this minimizer bra have underwire?

Yes, this is an underwire (wired) minimizer bra, so the wire helps lift and steady your bust for all-day support. If you'd rather go without a wire, the line also includes a Smooth Wireless Minimizer Bra. Both are built for everyday comfort.

How do I find my size?

Take the Fit Quiz or use Find My Fit to get a size recommendation based on your measurements and shape. This bra comes in bands 30–48 and cups AA–I, including half-cup sizes, so you can get closer to a true fit. If you're between sizes or unsure, chat with a fit stylist for a second opinion.

What's the return and exchange policy?

You're covered by the Perfect Fit Promise, with free exchanges for 60 days if the fit isn't right. That gives you time to wear it, check the fit under your clothes, and swap sizes if you need to. If you're still unsure, a fit stylist can help you dial in the right size before you exchange.
