I'm a 30" inseam, and average weight woman; for "lounge" wear, I usually buy a "Small" in men's, or about a size 10 in womens (I would choose a size 6-8 for "dress clothes or jeans, but I like a loose fit for sleeping, lounging...and, you know, my "eatin' pants" :). I bought the size M, after reading all the reviews that cited "shrinks dramatically after washing," or "too short," etc. Well, the reviews are correct. While the waist size of the Medium is a bit too large for me (I roll it once now, for better fit), the length is just right for a 30 to 31" inseam. I'm keeping them because it's SO hard to find a truly soft enough, and light weight enough cotton for Florida fall and winter season, where there's just a bit of a chill, but not really COLD. These are perfect weight. I also have hyper-sensitive skin, so I have to wear most pants inside out, as the seams cause irritation along the entire length. For those of you with similar challenges, these do, sadly, have exposed inner seams, and you will have to remove 2 tags, on inner tag, and one outer on the (gratefully covered) waistband. These are not "fashion pants," and I would not wear them out of the house, but they are extremely comfortable baggy pants type, soft cotton loungers, that run a bit short in length, and large in waist, as one typically has to buy a "too large" size waist to get a "just right" length leg. If you, Amazon, or the Seller, want to send me a size Small to try, I'll honestly review that size for fit and length, but I've already paid for these, washed them, and worn them...so I'm keeping them as my "comfy warm indoor loungers." Awesome soft cotton, baggy fit, perfect length for a 30" inseam. Good sleeping, lounging, or "eating pants," for wearing in one's home (when not expecting company or neighbors :).
