this is a terrible dress to take in
to do it correctly, you will have to undo the waist 3/4 of the way around to take in the bodice without messing up the gold & lace trim on the waist. Otherwise the half circles will be weird wedges and the lace lumpy in the taken in areas.
While you apparently feel it needs to be skin hugging, it doesn't look bad or baggy in any way
. It looks good now. I'm going to call this "more effort than it's worth" and say just enjoy being able to move easily in it.
