I ordered these in a size small. The package said small. When I opened it all the shirts were medium

I probably should have ordered a small. I am having to pull them up quite often during my workouts.

I compared these to some undies I got from Just My Size labeled with the exact same size and these are a lot smaller. ?? Why would they label the product with the same sizing but make them much smaller? They fit, but barely enough and it's uncomfortable. If you get these, get them a size too large, maybe.

2 STARS because they do not fall apart with washing/drying like most of the plus sized undies I have purchased. These are well constructed, but way undersize as labeled.

Since I ordered a small, and was shipped a large, not once, but twice, hard to say, but I would surmise that the fit runs somewhat large.

I ordered these large, they are petite, I can't pull them up past my hips. I usually wear medium, and got large to be safe. The product is made for micro-people.

I always wear a small in leggings but these size Small were so little, I couldn't get them past my knees. They were cute leggings though. I am going to attempt to return them.

Thought they would be a bit small but they were actually a little larger. I would order I size smaller next time.

The panties are cute, but when mine arrived (in factory packaging), there was one pair that was randomly 2 sizes smaller! It was the same color as in the other pack, just a mispick, I guess. Needless to say, those ones are too small

They looked like they would fit fine, however I found them to be smaller than expected after washing them accept instructions.

A friend gave me three pairs of these socks in Medium.  I decided to order more pairs but the socks in this order fit like a small even though they are a medium as well.  I was really disappointed in them.

I ordered medium sized  and the packaging said medium, but the underwear was all large-sized.

I ordered a small, and these were EXTREMELY small. I am typically a 2 in pants, and nothing fit in these shorts.

These seem to be a bit small, but they are comfortable

I was disappointed when i received my package with these inside. I could not believe how to tiny they were. I'm not gonna even really be able to use these for anything. The seller shipped them promptly though. On the site it's not clear how tiny they are. And the pic is deceiving, it appears  bigger than actually is.

They looked small when I took them out of the package, but they stretch a lot and leave NO underwear lines!

I ordered 2 pairs in different colors.  They are 1 whole size too small and do not come in a size bigger than 10.  Cute colors and fast shipping.
