When I googled this pattern or looked at reviews, I didn't find a single photo of someone wearing it post-partum. My guess is that new moms are just too busy to blog about a garment after baby arrives, not that this pattern is particularly bad for after pregnancy. In fact, I'm quite pleased with how it looks compared to other stuff I have in my closet.
In these photos I'm five days post-partum, with the lovely no-longer-a-baby-bump and giant nursing boobs. Basically, a lumpy mountain range. I think the cut of this top, combined with a busy, colorful pattern, is doing a lot for me. In a solid color the lumps would be more obvious, but you can't help feeling cheery in this print. When I was pregnant I felt like this top was a bit tent-ish, but seeing it on the other side I'm so glad I made one. I wish I would have taken it to the hospital with me to wear home!
One downer: it was washed with a swimsuit and the dye bled, even though I had already prewashed the suit alone. So now it looks like I tried some stupid tie-dye effect on the blue part. Waaaaah. At the very least, I can wear this shirt around the house and feel more put-together than I would in sweats and a baggy tshirt.
