Dress Form Advice Please

As a new sewer I do not have all of the specialty items that help to make it easier to sew. I am trying to stay somewhat vintage in how I do my sewing. True to the times so to speak. But I am at a bit of a standstill on a dress, because I can't fit it properly all by myself. It is a reversible dress and I may have chosen the wrong fabric...but will not give in on making it into something wonderful.
I need a dress form to finish this. Any suggestions on what best to get. I am small on top 32"-34" bust and have a waist of 27"-29" depending on how much I want to breath (damn turning 50 has thickened the waistline.) I finish off with a bodacious hip of 38". So as you can see...I am bottom heavy and want a dress form that will match my shape. I have thought of making one...but it seems hard. This makes me a size 6 in todays clothing and somewhere between a 12 and 16 in vintage patterns. It is all so confusing, but I want my garments to fit. I am also having trouble with the darts (which appear up around my chin :) in some of the vintage patterns. I will need a real pointy bullet bra soon.

Thanks for any help. I f my hubby gets home anytime soon I will add some pictures of the improperly fitting, hanging dress.
