I just got Generation T from the library and was disappointed to find that all the shirt ideas are made for girls who don't require BRAS! Even when I lose weight, I still have great big gozongas. What is a big girl to do?
I made one shirt straight from the book, measurements and all. It fit alright, but barely. My man LOVERD it, but I could never be seen in public that way. I was ready to fall out of both sides! I decided that everything in that book needs to modified for girls with any kind of curves at all.
Here is what happened when I modified #46 Cover Girl, starting on page 118.


The measuerments call for 9in across the bosom straps, then gather them 3 in. I had to make mine 12 in. I still gathered them 3 in for a total of 9 in. bosom coverage. But then, because my girls wanted to separate, I added a brooch in the center to pull them together a little.
The last adjustment I made was to cut the back into 3 tieing strips. The book suggests one. But with 3, you have one high enough to help hold yer tits and the other two assist in keeping the whole shirt from riding up on yer gut.
It is extremely comfortable and airy.
You shouldn't much need a bra for this, but there is still the strain on the neck from the halter. Nothing to be done about that.
Anyway, good luck. i hope this advise helps a few of you NOT waste t-shirts making stuff that's too small!
