Advice/solutions needed for too-big dress made with cotton yarn
I am working on the Dimensions dress by Mermaidcatdesigns and about 2/3 of the way done. Using sport weight, 100% cotton yarn with a C hook
Photo 1 of me in the WIP, photo 2 of the pattern
Originally it was fitting great but as it's getting longer and heavier, it's stretching quite a bit and starting to hang really baggy on me vs the form fitting style of the pattern.
Should I continue making the dress as is and then intentionally shrink it in the wash (since it's cotton)? Do I block and then sew up the sides to fit it?
Would love any feedback.
(Please ignore the stratches on my chest, I have dermatagraphia and they show up whenever I change clothes 🙃)
