Son de algodon pero son muy finosMaterial nice very soft but didn’t last too long after few washed starting to ripped off at edges elastics parts.These fit snug and don’t stretch like most panties. They do the trick but we won’t get much use out of them since the stretch is limited. I wouldn’t buy again.My wife bought this for our niece. She seems happy with them.XS. 2-4. XL. 12-14S. 4-6M. 6-8L. 10-12My girls love the patterns and I love the cotton material. They're soft and comfortable. Two of the pairs have a different, thicker waist band, and they fit more snug than the rest. Not sure if the company put the wrong two pairs in the bag but we're keeping them regardless.These are ok, the seat part is a little too narrow, i feel like that would cause them to be uncomfortable but my daughter hasn't complained yet. Also I think these run small. My 3yo is in 5t clothes so I ordered a small & they aren't too tight yet but definitely more snug than other brands I've tried In the same size. The M would have been betterOkI bought Trimfit Girls 100% Cotton Colorful Panties (Pack of 10), Pink/Blue, Large / 10-12. According to the package, they are intended for girls weighing 67-84 pounds.I bought them hoping that they would be Days for Girls size GS to GM (recognizing that the individual sizes vary even within one package, and FOTL size 14 are usually DfG GM to GL). But these are quite small, the first two I measured were DfG size GXS. I am returning them. The quality feels good, and the price is right, however!Very little give. I have a 2.5 year old. Figured I’d buy some new underwear for her. They are very stiff the elastic isn’t very good. One pair is already ripped at the seam. I will not buy them again. I’m not very impressed. But I guess for the price I should have realized that.The waste bands are too small. I stretched them to get them to fit my petite daughter's waist and the fabric has already separated from the elastic. Will not recommend or buy again.My child is true to size and these looked like they would fit except there is so little stretch in the bands that it was very tough to pull them up... So they essentially are too small simply because they don't stretch like normal undies. Also a weird high cut that was almost high waisted. She hated them! Not very soft either.They look and feel like cotton undies. I docked a star because there is a tag inside on the side that doesn't need to be there! I had to cut them off wveey single pair, such a pain.
