When I took these photos, I didn't take any separate images of the onesie, so here are parts 2 & 3 of this outfit together. For the onesie I copied this idea, just downsized it a bit. Started with the flowers and sewed them on this knit piece.
Then I ruffled this black knit piece and left it pinned down while I sewed the top piece on.
For the bottoms, I just replicated the process from the bib to the back of these cute little tights.
Once my sister-in-law welcomes her little girl into the world, we can pair this outfit with a cute little body and face.
