You mention the pocket might need some adjustment to keep the form in place. That is exactly my need. I have the crinkle high neck suit you picture above. I love it but to fit hips etc the suit is a 16. The bead-like forms I want to use are a size 5. I don't know how to anchor the forms. I've tried safety pins but would like something more permanent. How can I anchor the forms permanently in my swimsuit?
I would suggest Velcro. However, they are not all the same. If you have a fabric store near you, they will offer various thicknesses. Some may need sewing and others may have an adhesive. What you'll need is a thin but flexible type.
The assistants will be able to show you, but things to consider are: it will likely be exposed to chlorine, and also you want one that, should it come into contact with the skin, won't cause irritation or rubbing.
