Great looks for any outfit choice
Size: 12 Toddler, Color: Black/Grey
I was proud to see my first grader run their first mile on these shoes. The look and color is great for either a boy or a girl, and matches with either neutral colored or bright outfits. My kiddo found it easy to put on and adjust snuggly, so it’s nice having a shoe that doesn’t require an adult to calibrate and tighten just right (like my kids soccer cleats!). This is several steps past your cheap sneaker and I can tell it will comfortably get many more miles from my kid.

A good choice
Size: 4 Toddler, Color: Black/Grey
This is a great pair of shoes with excellent durability and color. It’s a classy little shoe that looks good and had a good fit. That was true to it sizing. It’s an excellent value for the money and they held up well throughout testing. No flaws were found in any of the materials and workmanship was phenomenal. If I could give it more than five stars I would.

Attractive Hoodie for Women Too
Size: Medium, Color: Pink
I'm female, weigh 110, 5'6". My family member is 5'7", 165. We both like the Medium is this French Terry zip hoodie. The cut is generous and proportioned nicely. Its long enough to fall well past the waist. The cuffs are soft but stay if pushed up. The fabric is soft and comfortable, and warm. The hood has two seams, so it lies nicely. This hoodie seems well made. The interior of fleece hoodies eventually pills up and stiffens; this fabric won't do that. Washed in cold and dried briefly then hung up, they don't shrink much if at all. The price is good for the quality. The dark pink is a good dusty rose color. The heather gray is a classic medium gray.

Nice hoodie
Size: Large, Color: Teal Blue
A nice, light hoodie. The teal blue color is bright and cheerful. It is true to size. The reason I didn’t give it a five star rating is the inside is not the usual fluffy soft surface of a sweat shirt. It is more like a fine, short loop terry cloth towel. It is comfortable but different.
