So I realized I had 5 shirts all within the same color family that were not maternity-friendly and realized I don't need 5 purple shirts. So I left the stained tank as-is and cut 4" wide strips out of the others.
I gathered the strips and sewed them in a somewhat hap-hazard tiered fashion onto the front of the tank, starting just below the bust line. Basically I was trying to copy a shirt my daughter has that I love.
At first it seemed really odd to leave the back empty, but I didn't have enough strips of fabric to cover it too and it had a slimming effect (not like I need that now, but in a few months I might appreciate it).
It's super comfortable, and should be wearable after I have the baby too.
Here's a closeup so you can see the little zigzags I used to attach the strips to the front. I kinda like that they turned out a little wonky; it's less store-bought/perfect looking. Come back tomorrow for another transformation! Just 2 more before I hit my quota!
