Its true, and unless you get something commissioned to your exact measurements, there is a high chance ordering things blind online will end up a waste of money since you can't try it on ahead of time, and ebay and etsy sellers don't typically take returns if it doesn't fit. This is of course if you want a bodice with any kind of real boning (I cannot tell the type from the pic you provided). But, if it doesn't have boning, its more like a vest and the sizing will be more forgiving and you can find it cheap. Most cheap real bodices though have cheap plastic boning which can break or bend easily, especially if you have any kind of curve to your form. End all is best bet is to wait till you can afford one with real steel boning and can commission your size exactly from a seller if you have trouble finding a good fit, or wait till spring/summer ren faires to try things on.
Damsel in this Dress might have something like what your looking for, and she has an etsy site that at times lists things for custom sizing if you don't want to directly commission something, and prices range from 65-400 dollars, depending on the corset/bodice. (

Moresca has a website (see above) and has open houses in the spring and summer, and is at a couple renfaires. Returns with them is also relatively painless if you want to order early, and while they are more costly, I and many others can attest to their quality and ability to hold up to years of wear and tear - also they fit all sizes.
Good luck!
