These pants are absolutely stunning! I wanted to get a pair of stylish stretchy pants that were flattering but also comfy enough that I could wear them on a long haul flight from NY to Korea.I originally ordered this in a medium and while it technically fit there was no way I could sit in them for 14+ hours — it was pinching me in the knees. I had to shimmy to get into them & as others have noted, when they’re skin tight the zipper sticks and the button does seem like you’re seconds from breaking a window if it pops off.I exchanged them for a large and wow what a difference. I’m by no means curvy but I do have a little bit of a bum/hips and I’ve always had defined calves. I’m 5’5 and about 150 right now. I can normally wear a medium but not in these for extended periods. The large hugs me without being painful and they’re so comfy I want to sleep in them. There’s no gapping and the weird ankle issue others noted that I saw In the mediums aren’t happening with the large.So if you profile isn’t LITERALLY a straight up and down line, please do yourself a favor and go up a size if you want to do more than wear these pants for an hour while standing upright the entire time.Ordered medium (6-8) 5’8 145 lbs and they fit ahhhhmazing!!!! Great quality!I really love these pants! Pictures don’t do them justice but I tried to take photos that would show you how electric blue it is and how stretchy it is. I have a large bottom. Hips measure 48” around bc my butt be poking!! I’m currently on my weight loss journey so I bought these knowing I would test the limits. These pics were taken when I weighed 220lbs. I’m 5’7”. When I wore them to the event I bought them for I ended up weighing 215lbs that night. They stretch A LOT but I think my measurement is basically the last point by which they are wearable. They are not sheer at all. The night I wore them my period panties did not show a line or anything! They are high waisted and go up very far and imo provided stomach support. You can kind of see it doing that in my photos and I do have a gut(runs in my family*thanks dad!!!*) I haven’t measured my waist yet but the button was fighting for dear life until I hit 215lbs. I’m currently at 211 and they continue to fit better. I highly recommend them. I got stopped a lot and asked where to get them and received many compliments that night. Can’t wait to wear them again. I’d eventually like to buy the other colors some day. Anyway, I hope that helps.fit perfect but if you bigger than a 16 this may not fit.At most these are worth $40, a bit pricy for being made overseas. Nice quality for cheaper material though. I’m 110lbs, 5’4 with wide hips and skinny legs. I ordered XS after reading reviews but if I was to gain one pound they would not fit. They are beyond snug on the hips, thighs, and waist… but loose around the ankles. I might return and get a small. If you don’t have wide hips you’ll be fine. I do love them though, they are super cute! I’ll probably get a small and have the ankles tailored. I love that they don’t press my butt in even though they are tight, they shape it nice. They look expensive on but off you can tell it’s a cheaper material.These pants make me feel like I’m walking lava lol. I had previously bought the black version for work and decided on getting the red version because it’s my favorite . Thick enough to feel warm but lightweight at the same time . Forms you’re body well. I’m not used to pants being so high waisted on me but they are very flattering to my figure . For reference I am 5’4” 138lbs and bought a medium. True to size.Not sheer, sturdy fabric. Very flattering and boy howdy, these will feel like they’re painted on. I’m normally a size 8/10 in pants or 30. Went with a medium and I definitely feel nervous with how tight the button is and like they’re gonna rip at any moment lol but they held up completely awesome the 3x I’ve worn them out. Obsessed. Can’t wait to buy another in black.Awesome quality! Well made! Lovely fit! I’m keeping it!These are top quality, I bought them for fancy having tried cheaper ones, these fit well and feel much nicer qualityFit great, very happy. You can tell the difference between these and the knockoffsReally good quality and fitI ordered XS. Def a snug fitI’m 9st 4 ( I’m 5ft 6.5)no room to put weight on to wear these in XS sizeI would need a small if I doThe quality of this product is terrible. Its so cheap and tatty. Really disappointing as the pair I bought from American Apparel a few years ago were good quality and lasted years. Definitely not worth it, don't waste your money.Like the overall fit but the length in the legs was too long. Would be good if the disco pants came in other leg lengths for us mini people.
