Making my own bra is something I never thought of. I also saw @nineclaws mention that she should make her own. That's a clever idea.
I think you're at an advantage since you already make swimsuits 🙌

Yeah, our bodies will change regardless, and the older I get, comfort wins.

You've reminded me that I should probably get some new swimwear instead. That way I can double up wearing the tops as bras while I'm in Jamaica, and actually get good use out of them while I'm there. 😁
