This is my first time posting something I've made.
The acquaintance (we'll call her C) saw a tanktop on a maternity website for $200, asked me if I could make something comparable. I said yes, I can. And I did. I got nowhere near $200 for it, though.
The shell is the confetti dot fabric from Joanns. It was a pain in the toosh. It rolls, handwash only, you can't iron it, and the glue from the dots sticks to the needle. The lining is also from Joanns, it's a posh black lining, very soft. I happened to have a Butterick maternity pattern that I used; I don't remember the number but can dig it out if you want it.
It was originally a t-shirt type of pattern but I omitted the sleeves and took a bit off the shoulders.
