I think leggings are still in and can be appropriate for all women at any age. As we move into fall, I have seen some great jean leggings that are perfect with boots. Otherwise, I think the full length legging vs. the crop is preferable. I don’t feel like my legs look larger in them, but I think that’s because I typically wear black or chocolate brown leggings. I bought one pair of gray and haven’t worn them because I didn’t think those were very flattering. For fall, I would definitely recommend the jean leggings.
