Rated 5 out of 5 by Our One and Only Underwear My daughter had a difficult time with underwear for a while and on the advice of many people, I decided to try these for her. They're perfect and she loves them, finding them comfortable. They also wash extremely well. June 6, 2016
Rated 5 out of 5 by Didn't solve our problem, but does have great features. We have tried multiple brands of underware to find a pair that doesn't give my six year old wedgies. I saw that some reviews said that this product helped this problem so I decided to give it a try. Unfortunately, my daughter is still complaining of these underware giving her the same problem. Although they didn't solve our "riding" issue, I love how modest they are. Never have I seen a pair of little girls underware that completely covers everything and stays that way with movement. Also, they are super soft and look like they are made well. So either way, they were worth the money! June 1, 2016
Rated 5 out of 5 by Perfect Just wanted to submit a review for size reference. I was a little worried about what size to order based on the reviews and the tight leg openings that other reviewers mentioned. I ordered the XS for my tall, 24lb almost two year old. They fit her really well after washing. Still slightly baggy, which is fine by me, it will just give us extra wear time. The leg openings are fine, definitely not too tight. Good coverage, they don't ride up at all, and I love that they're organic. She loves them too! May 31, 2016
Rated 5 out of 5 by My daughter either wears her HA unders, or she will not get dressed! My daughter is now 4.5 years old and has been wearing HA classic unders for a couple of years now. Life before HA was quite frustrating. My daughter was accustomed to having her diapers with full coverage, and she would not accept the skimpy department store underwear once she was out of diapers/pull-ups. I searched store after store and tried multiple packages of briefs. She would not wear anything! Short of having some custom-made, I searched online and found discussions about HA classic unders. It seemed to be the answer to my prayers, so we ordered some. Needless to say, they were a hit from the start! She first started with the training unders (the biggest size available), then moved up to the big-girl classic unders. She absolutely loves them and will not wear anything else! May 27, 2016
Rated 5 out of 5 by Excellent as always! The only underwear my daughter likes. Well made, super comfortable! These underwear never wear out. May 17, 2016
Rated 4 out of 5 by very soft I wanted to try Hanna undies for my daughter since all the reviews raved about them. I ended up getting the extra small because I was afraid the small would be too big. My daughter is a couple months away from her 3rd birthday but wears a 4t in other brands. The Hanna's do fit, but they are a bit tight at the leg openings. I just stretch them out and they seem to be alright, she doesn't want to take them off! May 12, 2016
Rated 1 out of 5 by she rejected them immediately I ordered small for my petite but muscular 42 lb 48 inch 8 year old. She refused to even try them on. If I hold them up to her the waistband comes half way up her chest and its huge in diameter. I agree, the sizing is waaaay off. I considered the hipster style, but it looks like it would ride up and she would never wear them. I'm tired of wasting money on underwear. She still wears size 3T Gerber training pants, washed and stretched out for 5 years, because they don't ever ride up and they sit comfortably on her body. I continue to try to find her comfortable big girl underwear but forget it. May 7, 2016
Rated 1 out of 5 by What happened to the sizing?! Our older child has been wearing Hanna unders for almost 10 years. They wear like nothing else. So we went straight to Hanna when our toddler was ready to move out of diapers. The sizing is totally off now. Our average sized three year old could not get her legs through the legholes on the XS which by height & weight guidelines is her size. We re-ordered in an S and it's great that she can get her legs through but they're huge everywhere else -- they pull up past her belly button. We ordered more for our older one in her current size L and once again, she could not get her legs through the legholes either. Store was great about exchanging sizes but so disappointing. Never in the last 10 years have we ever had this issue. We bought a dozen pairs so don't think this is a fluke -- something is definitely off with the sizing. April 23, 2016
