I love Zuntano and Hanna Anderson. I always look for them at thirft stores, but only now and then find a Hannah. I do buy Hanna's new and on sale at their website. Both are well made and worth a bit more money.
Hanna Andersson! Whether we're buying new, getting hand-me-downs, or buying second-hand, these are by far our favorites. They really do last season after season, year after year. The best hand-me-downs ever! And their website has really good sales from time to time. I never "got" the hanna hype until I bought dd two new sleepers, one hanna, one garnet hill (another high end natural fiber brand). When you lay them both out together, they were almost identical dimensions, but she was able to wear the hanna one many months before the garnet hill because of their clever design with the snug cuffs that allow for lots of growth - the garnet hill one still flopped over her feet. And then, once she was wearing both, the hanna one (despite months more wear) was crisp and new and the garnet hill one quickly faded out and started wearing in the seams...and the hanna wore on and on and on! I like the value of hannas - they really have done a lot of work on designs that fit for a long time, they wear forever and hold up to hard use, and they have lots of cute and simple styles.
We like Hanna but will only buy it new at the outlet - we heartily recommend taking a grandparent along.
We like that many of her fabrics meet the European Oeko-Tex standard which guarantees that the fabric is free of pesticides and other nasty things.
Otherwise we buy things that appeal at the thrift store or at garage sales. We also have a lot of hand-me-downs from an older cousin and two neighbors. I also aspire to knit more, ha ha! If there is a specific item I know I want - like I know I will want another pair of the gap denim overalls made from the lightweight denim with the soft jersey lining - I will look on eBay.
We too hate logos and highly recommend buying a stitch ripper at the fabric store if you don't already have one. We have ripped many logos and labels. If there is fading and you can see where the logo was and it bothers you, you can buy a cute patch and sew it over the spot.
