I bought a pair of these leggings with my first pregnancy and they are truly the best leggings. Since we can't go into stores to try things on right now, I did a big online search to find the same leggings in the same size. Unfortunately the company seems to have changed the formula - the material is much thinner and the sizing is much smaller, making the S/M much tighter than my initial pair. Not sure how much longer they'll last me in this pregnancy and they just arrived. If you're trying these for the first time, you'll probably still love them, although the material is not as soft.
