I bought the two-pack of Black and Rust in a size 6m. They fit as expected per the reviews I read and the sizing chart. My daughter is 3.5 months and they fit her wonderfully! They're just a tad long right now, but no problem bc I just rolled the waist band once. These pants are SUPER SOFT! I love them so much I just ordered a second set, the black and taupe. The reason I gave 4 stars instead of 5, is because I wish there were different colors in each set, instead of one black pair and one other color. I want to get all the colors, but she doesn't need that many black leggings lol
