Reddit reviews Demystifying Bra Fitting and Construction

Because I only added the extra width to the centre of the lower cup, there was no need to change any other pieces of the bra. I hope it makes sense with the photo I added.

If you haven't seen it, have a look at this book. It's written by the pattern maker and is fantastic for understanding how to fit your bra. It explains it a lot better than I can!

Ooh, that is tough! TnkrbllThmbsckr has a good suggestion about having a friend or relative help you.

Another option is to learn how to alter or make your own bras. Here's a book I'm thinking about purchasing (maybe you can order it on Kindle?) http://www.amazon.com/gp/product/B00C9QYV3U/

Here's another DIY resource: https://www.bramakerssupply.com/site2009/cart/shopdisplaycategories.asp (they ship internationally)

Good luck!

Unfortunately, most bra patterns are designed for matrix sizes using +4 fitting and with almost no known variations for shape. I'm afraid you may need to experiment, but that's not uncommon for bras. Try sister sizing up to a 30A and see if you can adjust the fit? You may also want to look at patterns that don't appear to come in your size, and check the size chart to see if they cover your measurements instead - could work out, could be a +4 disaster that results in too large band and too small cups, can't say for certain.

I've had this book on my wishlist for a while now, and this one.

I intend to get into making lingerie making myself. So far I have bought the Orange Lingerie book: https://www.amazon.com/dp/B00C9QYV3U/ref=cm_sw_em_r_mt_dp_U_BGS3Db9Z8AF0Q

And purchased some classes on Bluprint:

Some of them are available on DVD but not all.

I also saved this YTer making a popular bra: https://youtu.be/HRepyjHNcJg
