Measurements for Reference: 5'4", around 150 lbs, muscular with a little fluff :)I LOVE these QueenieKe leggings and I now own them in six different colors! The solid colors are made out of thick material, though it is not so thick that you can't workout in them (which I do!). I usually wear the solid colors for when I am doing upper body because they do show some sweat in the crotch area if you're sweater like I am! I also enjoy wearing these leggings hiking or just out and about on errands because they are so comfy. I wear a size medium in the solid colors and they fit really well. I don't have any pictures in them, but they have held up beautifully in the nine months I have worn them.The space dye material is thinner and stretchier, which I love for leg day! I have the space dye in two colors (grey/black and blue/black) and I got one in a medium and one in a small. The medium grey/black pair fits well in the waist and thigh area, but are slightly too long. They have also held up really well in the nine months I have had them (wearing them once or twice a week). I just recently ordered the blue/black space dye (shown in the pictures) in a small and they are PERFECT! The material is slightly different than my other space-dye pair, but I actually like it better. The waistband has also been improved and has a thicker band that keeps things in place nicely. The length is awesome and I will definitely be ordering more space dye colors in a small!In short, I highly recommend these leggings for anyone who is looking for a quality, well priced, and cute pair of everyday/workout leggings. I suggest sticking with your regular size in the solid colors, but try sizing down in the space-dye colors because those run a little large.
