(Also, does anyone here have all their measurements fit one standard size? Or does everyone have to deal with weird sizes? It seems ridiculous to me that there is a 4.5 size difference between my waist and hips- I have a figure dammit!)
If its any help there are 10" between my waist and hips as I'm 32-23-33, so its not just you!
That doesn't sound so bad. The difference with my waist to hips is 12" and between my bust and waist is another 11". The size charts that were given with the link, if you got a chance to look at them ( http://simplicity.com/index.cfm?page=section/fittips/meas_charts/ei_measchar.htm#misses_misspetite
), you could make a size 8/10 for the bust, 4 for the waist and 6 for the hips. The smaller the sizes, 4, 6 and 8, the less of a difference there is between them. I think I may have mentioned it in my comment above that these three sizes have only 1/8 - 1/4" of an inch between each cutting line on the pattern, and as you get into the larger sizes there's 1/2" and more between each cutting line which if altered incorrectly could make some strange looking seams on a garment if you were making a big size difference between the waist and bust/hips.
As for the link on how to adjust for a fuller bust...I didn't find it very helpful because the problem I always have is my bust is much bigger than my underbust, so how do I alter a pattern to make it fit my boobs but also make it fit my underbust without it looking too awkward? Especially if some of the patterns I have don't have a seam running under the bust so I can't add bust darts like the ones commonly found on an empire waist.
