Wanna do it right? Hand wash
We know it’s a drag, but the surest way to make your Thistle and Spire last is by hand washing.

1- Soak with a delicate detergent or lingerie wash for a few minutes in the sink, working suds gently into the fabric, and rinse thoroughly.
2- Press against a towel to remove excess water
3- Hang to dry

Ain’t got time for that? Machine wash
We know you’re busy. The next best option is to machine wash in your Thistle and Spire laundry bag.

1- Place intimates in your T&S laundry bag and zip, don’t forget to hook your bras together.
2- Wash on cold.
3- Hang to dry (Heat from the dryer breaks down the elastic and spandex, making them fall apart sooner).

How to find your perfect T&S fit

The easiest way to find your size is simply by measuring, get started by putting on your best fitting non-padded bra.
Bust: Stand up straight and measure loosely around the fullest part of your bust keeping the tape parallel across your back.
Underbust: Just underneath your boobs, measure snugly around your ribcage, keeping the tape parallel across your back.
Waist: At the smallest point of your waist measure loosely keeping the tape parallel across your back.
Hip: At the Fullest part of your hip and butt, measure loosely keeping the tape parallel around the front of your body.

Bra Cup Sizing:

Hey Sister Sister! There's a trick to finding similar bra-sizing with sister sizing. Sister bras have the same bra cup capacity even though they are different sizes. Each row above contains corresponding sister sizes. For example, if you are a 38D, you can also try a 36DD.

Bralette and Bra Alpha Sizing:

Our alpha sized bras and bralettes are highly adjustable so that they fit a wide range of customers. We recommend that customers with fullers busts size up and adjust underbust bands down. If you have a fuller bust, you can check out a list of recommended bras for here.


Panties, Bodysuit and Sleepwear Sizing:

Hey babe, concerned about bodysuit sizing? We suggest sizing up for lingerie lovers with longer torsos. 
Unsure about your size? Email us at with any sizing/product questions. We are happy to help you find the right fit!

Why can’t I find my size?

If we do not carry your size, we are very sorry to have let you down. You can contribute to this poll here, which our team reviews quarterly to understand what sizes you are looking for.

We are a tiny company and don't have the capability to make the entire bra size range just yet. A great deal of time and investment goes into perfecting and engineering each and every size. We want to make sure that all sizes fit perfectly when we do expand our size range. It is our long term goal to grow the size offering. We are working towards that goal, but it's going to take us a little time. Thank you for your patience

Why does it take so long to grow your size range?

Our story started when our founder decided to quit her full-time job and take a chance designing her own line of lingerie. She did this without any deep-pocketed investors so she started with a handful of sizes and we've been working to grow that since. Each and every size is an investment when factories have high minimums. We're growing every aspect of the business as fast as we can with the limited resources we have.     

How are Thistle and Spire products made?

In order to provide beautiful and obtainable products we work with a small handful of high quality lingerie factories in China. These factories are all complaint with local health and safety laws to promote healthy working conditions. In addition our Head Designer and Founder personally visits and inspects every factory we work with in order to meet the workers, and evaluate the suitability of the factory work environment. It is very important to us as a company to provide the best product that we can, in addition to providing a safe and comfortable environment for the people who manufacture these garments.
