Im going back to school in my 30s, which obviously led me to leggings-as-pants jealousy- somehow every 19 and 20 year old has at least one great pair of non-see-through black leggings. Now, I haven't made it into the rec center in my time on campus, so I don't have a 19-year-olds body. Usually leggings slide down on me if they're not good quality and a little big high-waisted. I also get a bit of a muffin roll in unkind pants.

Ive tried leggings that go for over $100 before, but, while they were pretty nice, maybe not enough for the price. I found these after a quick google search for best black leggings. The article recommended these in particular in the tummy support category. They also recommended ordering a size up.

On to proper reviewing:
Sizing: Im usually a 29 in jeans or a L in pajamas and lounge pants. I got an extra large in these.

Opaque:  yes! Fabric feels thick- not to the point of being too warm on a moderately nice day. Probably could be nice for yoga. Im not sure how the fabric performs compared to leggings advertising performance fabrics. It feels heavy on the cottony end of the cotton/poly/spandex blend of most leggings, but with enough synthetics to bounce back.

Fit:  overall, snug without being spanx or a true compression tight. No slipping down in the thighs. A secure hug kind of feel in that area. The waistband itself was a bit looser. It still gives me a tummy control effect because its a thick smooth fabric over that area, but it wasn't necessarily squeezing that area in like womens garments like to say they will. Because of the waist, Id consider sizing down if I decide to order another pair, but I would be worried about the thighs being too tight in that case. I also noticed that the back of the waistband seems lower than the front. If I wore crop tops, Id be slightly worried about the back of the waist showing too much if I was sitting or bending over. This could also possibly be fixed with a tighter fit in the waist, which could just be a size or body proportion issue. Im about 56, and length is usually not a huge issue for me with leggings, and these, like most, were just fine in this area.

Quality/value: overall, these really feel sturdy and useful for anything from loungewear to part of a cute put-together outfit to yoga wear. They came packaged on a paperboard sleeve like they would be displayed in the accessory section of a store, which is usually a red flag for me, but Im pretty impressed with them. Presuming they keep their fit and shape, they seem like an excellent choice for their price range and Id definitely consider buying them again.
