I didn’t see a maternity-specific size chart for Leonisa shapewear, so I used the size chart provided to order a medium based on my pre-pregnancy measurements (28” waist, 41” hip). I typically wear a medium in Motherhood, Old Navy, Gap, and Loft maternity clothes. When these first arrived, they were pretty tight, but workable. I was desperate for something to wear under a bodycon dress on the day these arrived, so I kept them rather than go through the exchange process. First, I will say that I really like the quality. I’ve tried similar maternity shapewear styles from Spanx, Franato, Motherhood, and Bellevation...these are, by far, the highest quality of all the brands I’ve tried. I was skeptical that the stretchy mesh netting material that covers the belly and cheek areas would hold up, but it has endured several washes and wears without any damage. These also provide awesome support right under my bump and through my lower back. In that regard, these are my favorite over all the other brands I’ve tried. Most of the drawbacks I have found with these are probably related to the fact that I need a larger size. For me, the leg openings tend to roll up my squishy thighs, and I hate having to tug and smooth them down every time I stand up. I also find that the binding around my rib cage rolls down, digs in, and creates a backfat roll below my bra that is both hideous and extremely uncomfortable. I am constantly have to pull and adjust, and by the end of a full day in these, I’m absolutely miserable. Again, these issues are probably not faults in the garmet itself...they were borderline too small for me when I first purchased them, and I’m sure I have gained at least 10-15lbs since the first time I wore them. I just re-ordered in a large, so we’ll see if that helps at all. There is one design issue for those of us whose buns are not quite as toned as we might wish they were...the stretchy net material that covers the backside does not provide any compression (unlike other brands). For me, that means that my rearview is not quite as smooth as it could be, and there is more jiggle than I’d like, especially under form-fitting dresses made of thin material. This isn’t as problematic under looser dresses or dresses made if thicker fabric. But, this “flaw” may be a cool feature for women who like a booty-maximizing undergarmet. I, personally, benefit from a little more lift and hold back in that area. All in all, if you get the right size, I think this is one of the best maternity shapewear options on the market. It would be nice if the seller would provide a little more guidance to pregnant ladies whose bodies are changing rapidly since we can’t try them on before purchasing. I personally don’t find height and weight references helpful (since we all differ in body composition), but in case it assists someone else, I’m 5’9” and started this pregnancy at 150-155lbs (size 6-8). At 24 weeks, I’m now nearly 180lbs and still wearing mostly mediums (and some larges) in maternity clothes. This particular medium has become unbareably small for me. We’ll see if a large is better.
