Thanks for all the great suggestions for yesterday. Sadly, I've been to a tailor already with that dress. I should reiterate that I don't like wearing fitted woven dresses (at least ones fitted below the waist). I looked over some of my sewing books on alterations to make sure it's not just my tailor being lazy. The top right picture (from The Reader's Digest Complete Guide to Sewing) reconfirms that there isn't much one can do about pulling across hips, except let out more fabric.
And back to the shopping ban: I will still allow sewing new clothes for myself during the new year, mostly because I see sewing as a hobby, not as a means for accumulating clothing. Maybe someday it will be, but I like the creative process more than the wearing. I also like how I am learning more about clothes and fit from trying to make stuff for myself than from buying and wearing off the rack. Taking my measurements and comparing them to ready to wear and pattern measurements has been helpful. I know what parts of my body don't fit standard sizes, and therefore I can avoid certain off the rack styles (usually, many fitted bodices are suspect) and figure out how to adjust things.
Finally, totally unnecessary kitten shot. This little freak is 4 months old (estimated) now and he's getting bigger and stronger everyday. Buster does this when we don't let him eat our dinner.
