I haven’t bought anything yet, but plan to get some white tights and white long sleeve onesies or formfitting bodysuit things to help prevent staining.
Won’t buy anything dark and will wash everything first. My Mom likes pinks and pastels anyways so shouldn’t be a problem. 
I’ll be sending her very two different versions of Ever and thought they’d be cute (and practical) wearing protective white underthings and similar sleepers when I send them to her.
Not sure if she’ll decide one is a boy.
The second reborn will be a surprise for her. She doesn’t know what her baby will look like either, but I chose a sculpt she liked best out of a brief lineup at the beginning.
So lots of surprises in store for her when two babies and a little start of clothes for them arrives.
How fun for her!
It’s been a bigger project than I expected just to research and purchase them, but lots of fun for me too! I’ll try to take some pix of them together to post here before I send them off.
One is in the mail, and one will be sent next week, both coming to to me first in Oregon, then I’ll get them all prepped for mailing to Mom and Dad in Alaska.
