For this dress I had that exact experience and I decided to trudge through it.
this pattern I thought the bodice was made up of mostly gathers. Turns out it's all darts and after sewing up the bodice I realized it was a hot mess and it only got hotter and messier as I sewed the rest together. Other than the sloppy bodice the fit is good but the details annoy me.

The fabric is a linen look (meaning it's got polyester in it) that I bought on sale at Joann.
Maybe if I used a horizontal stripe fabric rather than vertical I'd like the bodice more but the bodice also has pleats in places and those look so much better than the darts so maybe it's just the pattern?
this is my "what was I thinking" face
I hoped it would be better when all the pieces were together but the final result is still a disappointment. Apparently Simplicity thinks my boobs ought to be three inches higher because the bodice is so bunchy right there (as you can see me pulling on the fabric in the pic above). Lumpy boobs is not a good look for me.
Maybe I'll re try this dress again someday only next time I'll gather and pleat the bodice to make the same effect and hopefully I'll get a better fit. Oh, well. At least this was a learning experience for me.
