FANTASTIC FIT
Size: 16 Plus, Color: Washed Blue
I'm a 4'7" , 65 year old woman. Due to abdominal issues I needed jeans that give that extra something on the waist. I've tried on just about every brand of jeans ranging in size from adult/junior 6 to 12. If they fit on the legs the waist was huge. If they fit on the waist the legs and butt had enough room for me and a friend. I was resigned to wearing yoga pants and leggings with big shirts. My son mentioned that he loved the Amazon basics men's dress slacks, so I figured why not. First I looked at women's and juniors, and I knew from the measurements that I was still stuck. Then I remembered that about 15 years ago I'd buy girls pants (I was a size 12 in kids at the time) Looking at the sizes I knew a 12 was way too small, then I saw the 16 plus. With hesitation I bought them. Well glory be miss Agnes, THEY FIT. Comfortable, real jeans again. Sure, I have to take them up about 6 inches, but that's fine, not a problem. I'm just so happy to have real jeans again !!!

Who doesn't love a unicorn?
Size: 2T, Color: Pink/Unicorn
Cute set but runs a bit big in my opinion for a size 2T. My grandbaby is tall for her age (22 months), but the pants were really long and loose on her, granted she's not chunky, so factor that in. Overall, it's a nice set and the material is soft (especially the pants) and seems like it would keep the little ones warm.
