It is a very comfortable piece of sportswear, suitable for winter or colder days, but not uncomfortable to use it on warmer days.I like how they fitGreat tummy and thigh(s) support. Color black and Grey not at all see-through which is very comfortable for me. Doesn't give me the lift to my backside I was hoping for. Overall I like the product..Love Love Love these booty lift pants and hubby does too! I am working hard on regaining my health & fitness. Currently I am down 10 lbs with at least another 40 to go. These pants are both very forgiving and supportive at the same time! I appreciate how they fit through all the movements that I do during my workouts. No sliding down and a major bonus is that no matter how deep the squat (as pictured above) you can’t see through them. I am 5’7 ish & 210 pounds. I bought XL and they fit perfect! I highly recommend these and just bought another pair!Very happy customer! :)Granted I do not have a bootylicious bum like the ladies in the product images. I am happy with how these fit , I’m 5’8 130lb and got a small. I am glad I went with small, fits nice , helps shape my otherwise flat white boring tushy. Considering doing some squats now ?. I was concerned that the unique texture on these types of pants would be too much.. in person it’s way less obvious than in the pictures. Overall very happy and may have to invest in a couple more pairs.I am 5’2 and 140 lbs, ordered a size M. My lower body is bigger than my upper one. My waist is 27 and my hips 39. If you have a smaller lower body I’d suggest you to order a size S. if you’re a bit bigger than me M would fit you as well.It’s not see-through and soft fabric and nice bright colour. Really good for the price. It is also a bit long but every pant is long for me so no problem:)So I just got these, the material is nice, its not thin so no "see through" issue. I am a bit of a big girl so I ordered an xl and they are not tight, it's actually pretty comfortable so which tells Mr 8 could have ordered maybe a large. The only small problem is the length I'm around 5 ft so the leg length is a little long (so definitely shorter women were not kept in mind) but that was fixable I just rolled the bottom up a little and now they look like Capri pants. Will probably do a bit of sewing to fix the length issue.I love the material but I feel like you can go a size down
