In this video I upsized a bodycon dress to fit my aunt! The chest fit perfectly but the skirt was too tight.
For everyone asking: I sewed the sequins using a regular needle that came with the machine (my aunts machine worked fine and my machine had no problem but it might be different for you). And since the dress is stretchy, I sewed with a zigzag/stretch stitch. If your dress is not stretchy then just sew with a straight stitch. I didn’t need to remove the sequins before sewing. I also sewed the triangles on BOTH sides of the dress, not just one side lol. Hope this clears up some things!

My aunt bought this dress from Fashion Nova!
