|Broken invisible zipper|
I replaced the broken invisible zipper with a metal zipper. Plastic invisible zippers can be easily damaged, especially if they are not very good quality to begin with. Always zip-up your zippers before laundering. This will protect the zipper as well as prevent it from getting caught on other delicate clothing.
I often add straps to strapless dresses that I buy at the store, but if you have a dress you would like to keep strapless, I would look it over and see if there are any places you can sew in a little Rigilene boning. The boning will add the structure you need to keep the dress from sliding down.
In my own designs, I always have built in structure for strapless pieces. This adds extra labor and material cost, so in the case when you end up with a dress that may not have the best support, sometimes there are steps you can take at home to improve a garment's functionality and performance with tweaks to the construction.
I hope these tips are useful.
