Just looked at Hanna Andersson....they have a lovely tunic and pants separates in velour.
My boys grew up in Hannas. They are a bit more expensive but worth every penny. They are the only sweats, similar to french terry, that two infants/toddlers could crawl around on the floor in and make it through both boys. I then handed them down to friends and relatives.
I expecially loved the one piece zip up sets in stripes. All my kids baby pictures are in Hannas.
Oh yeah, I had bought a jacket from them that the zipper broke the following year when the next boy could wear it. I called them, sent it off, and received an brand new jacket. That was service. I usually give a gift certificate to Hanna for baby gifts.
