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
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 my first order and I wasn’t sure what to expect. When the top arrived and I tried it on I thought WOW. Super comfy, fitted really well and looks like you have a strapless bra on underneath but without the discomfort of wearing one for prolonged periods.
The fabric is soft and the top is super comfortable and well made. Great top for the price. Will definitely buy another or two. Would love to see other on trend colours in this top for summer.
Really comfy - especially in the hot weather
I love these tanks - the fabric is so comfortable and soft and a great fit.
Love this top, feels amazing on and fits perfectly. I chose a size L and am usually a 12/14. Will definitely be ordering more.
Just arrived and my husband and I both love it. The lace sleeves are so pretty and this is the silkiest feeling satin I've ever experienced. Will definitely be ordering more in different colours because I'd like to wear this every night year round. Thank you!
Very wide V with open back. I love this crop top, it is very stylish!
I love this top. I ordered in white initially and it was a great holiday staple. I've now ordered in grey and beige as well as a cropped version in white. Its flattering and great quality
Very comfortable soft fabric & I love the inbuilt support.
I initially bought 3 of these tops and was so impressed with the quality, materials and how comfortable they are that have since bought several more styles and colours. The company itself is also very easy to deal with - would gladly have given 10 * if I could.
Great fitted top. No need for underlayers . Dress up or casual, love these tops. I'm size 10. I'm also a E cup. Great fit for the medium size. If only they could sell their products through Etsy again, for ease of a shorter delivery time to the UK. I would still definitely use this company again. I know which styles and sizes work.abd Anna is brilliant.
Liked the black one... Goes with lots of outfits, tucked in and out. Medium fit me well I'm size 10 UK and a 34E cup bra. Nice to not have to wear one.
Good customer service. Its a shame you aren't still with Etsy. Easier to get your products from the UK.
Too Beautiful, excellent quality .. Excellent quality, thank you seller. I'm very happy
