Sizing Guide
All our sizes are tailored to Australian sizes, our tops are generally close fitting garments if you want the garment a looser fit please order a size up.
If you are in between the bra size and the clothing size, we suggest to go the higher size. For example if you are a 12B but you normally wear a size 8-10, then you should order the size M.
Rest assured we offer exchanges and refunds if you need to exchange the garment for a different size or style.
You may see a fabric tag on our garments, you can ignore the size printed on the tag. eg. If you ordered an M, it may show L or XL on the tag.
The built in bra tops are suitable for Bra Cup Sizes A, B & C. For a size D we suggest to order 1 x size up and a DD order 2 x sizes up.
Here is a general sizing guide to help you choose the right size.

Let customers speak for us
Love them
Seller is just wonderful, I love these tops and have bought five different styles!
So comfortable, I love these tops!
Love these tops! I've bought several already.
Thank you!
Good quality, well made and so comfortable - fully recommend
Just love these tops so much that I have placed another order - so comfortable and fabric is top quality
Just love these tops - good quality fabric and very comfortable
Not only practical, but is aesthetically pleasing. Gone are the days, where you can see bra lines and lumpiness under clothing! Not only is your range, sleek and fashionable, but comfortable. Can't wait to see what you release next!
Good colour, fits well. Slightly on the small side .
Really great product, will buy more. If you're worried on sizing just email them, they will be able to help
Lovely shirt! Love the color.
This is the second top I’ve bought from Undo Your Bra and I’m so happy with my purchase. It fits perfectly.,looks fabulous and I don’t have to adjust the straps. The quality is excellent. I wish I had discovered Undo Your Bra much earlier. I will definitely buy more from them.
This is an AMAZING product, well worth the wait.
I was sceptical because I've had bad experiences before with built in support tops that have been shaped differently or been almost see-through but this t-shirt is really amazing.
I love how soft the material is and that you can't see ANYTHING through, it's extremely comfy and I just feel amazing in it.
And obviously the best thing is no bra!!
True to size, I'm a 12 and ordered a Medium, which would easily fit a size 14 too.
The delivery was far later than it estimated but when I enquired i had an immediate reply from the seller, which was brilliant and you can't ask for more than that.
I'll be buying more of your cotton long sleeve options, thank you!
