I bought this dress a few years ago and after the first time I washed it, it was too short for my liking. So I found two T-shirts that my son had outgrown and cut them. I added a small strip of folded white cotton between the addition and the dress and didn't even bother to finish the bottom edge of the dress because it is knit and won't fray. I wear this dress a lot in the summer. It is so comfy and I don't have to worry when I lift my arms up that I am revealing too much.
Cute suit, right? I bought it right after I had a baby and couldn't even try it on because I was 3 or 4 sizes larger than usual. I bought it in this color and black because I liked it so much. When I finally lost my baby weight and tried them on, I found them to be WAY too low cut. They looked bad. I haven't gotten to the pink one yet, but I did make a change to the black one that has worked out very well.
I cut some fabric off an old black swimsuit that I don't wear anymore and applied a ruffle to the neckline. It added just a bit more coverage, and that was all I needed. I feel much more comfortable in the swim suit now.
