I recently tried my hand at this for my new niece! My sister-in-law has beautiful (and rather expensive) taste in little girls' clothes. She set up a Pinterest board of darling clothes...so I just went through the board and chose things I thought I could re-create pretty closely. So far, I've made two items for baby Audrey but have fabric and ideas ready for two more.
These adorable little bloomers were from a French website. And they were $69 US!
This jacket was the second piece I decided to knock off. The original also happened to cost $69. That might be ok if it's a nice coat that can be worn for a couple seasons...but for a newborn that will only get to wear it a couple times, that's a bit expensive!
this pattern to make it.
