Hello! I'm appealing to those more skilled at sewing for a smidgen of advice. I've lost some weight and am much smaller in the bust now. I have a knit tank dress that is very forgiving and can fit over a large range of sizes, but now the armholes are really big and hang down to the bottom of my bra band. What is the best way to fix this? The three techniques that come to mind are
1. Lift at the shoulders and sew across the shoulder seam (with dress inside out, of course). The problem with this is that it lifts the neckline quite high.
2. Sew up under the arms, continuing the side seam of the dress.
3. Bust dart? I am aware of these but have never attempted one. It's sort of an angled line pointing from underarm to nipple, right, pulling in extra fabric from each side?
I'd love to hear from anyone who has experience in this kind of alteration. For the time being, I just wear a cardigan over the top. Many thanks!
