How much does it cost to get a dress taken in?

Depends on what needs to be done. Is the bodice that fits you actually too small in the hips? Are you judging by the table of measurements, or have you actually tried on this dress?

Taking in a bodice a couple of size can be pretty tricky, depending on how much too big and how the garment is made, it may involve having to totally recut the bodice ($$$). If, however, you can get a good enough fit just by altering side seams and straps, it should be a fairly cheap alteration job.

Unless your bodice is disproportionately small to the manufacturer's design basis, I'd go for the dress that fits best through the bodice, and requires only shortening straps. The amount of gathering in the skirt looks like it would be manageable for most body shapes. The side zipper makes it difficult to do a really cheap fix for bodice size, but the first thing I'd look at might be whether I could elasticize the back bodice and get a decent enough fit that way (with strap alterations).

Rough guess around me (I'm in the PNW US) would be $30-50 for alterations not requiring a total recutting of the bodice. When I was in Britain, I used to figure that most things I'd pay $1 for here would be a quid there, so I'm going to guess at least the dress price, and perhaps twice that, for alterations.
