I bought this brand / style of tights for my daughter when she started dance class at 3 years old. Back then, she wore the Toddler size. I love these tights so much that every time she outgrows a pair, I simply buy the same brand / style in the next bigger size. She's gone through sizes Toddler, Small, and Intermediate, and we're now on Medium. The sizes seem to run true-to-size. My daughter is currently a size 8, and the Medium (8-10) fits perfectly.

These tights are super soft and stretchy, and my daughter has been able to put them on all by herself since she was 6 years old, wearing size Intermediate (6X/7). (Back then, she had trouble putting on "regular" tights by herself, I guess because they're usually not as stretchy.)

None of my daughter's tights have ever ripped. I think the Toddler or the Small got a small "blemish" (a little discoloration, and the material felt thinner in that area) from when my daughter fell on her knee, but it never opened up into a run or a hole. Her current tights do have a couple snags in them around the knees, but again, they haven't opened up into runs or holes. Overall, I am very satisfied with the quality.

As an aside, I'll mention that one year, when I hadn't bought these tights yet, the salesperson who sold us ballet shoes talked me into buying Capezio 100% Nylon tights. (I think the store only carried Capezio brand tights.) After a few weeks of classes, both my daughter and I found we didn't really like them, compared to the Danskin UltraSoft Microfiber tights. They weren't very stretchy, so they were difficult to put on, and within a couple weeks, they had several snags. I quickly switched back to our trusted brand and style. I know this isn't the place to review OTHER tights, but just having that experience actually made me appreciate these tights even more.
