Simple way to fasten a wrap dress together

[partysong]

I have several wrap dresses that gape either are the legs or breast and need essentially a little stitch putting in but I am entirely incapable of anything that involves sewing.

Is there anything else I could try?

Little gold safety pin from the inside. Remember to take it out before goes in Washingmachine

Hollywood tape, unless fabric is really delicate works a charm. It’s a replace each wear thing usually

I wear a longline vest underneath in a suitable colour - long enough to act as a slip and no need to pin.

Buy some Stichless iron on fabric glue, and use it on whatever needs stitches. I found mine online.
