Mercy Lace Panty [BLOOD]

I originally ordered by usual size of M, but found that the panty was just a smidge loose on the waist. Since I like my panties to fit close to the skin, and the fabric had a small amount of stretch (A velvet polyester with 5% elastane), I bought another in size small which fit perfectly. I won't deduct any stars since the panties themselves are of wonderful quality and are very cute, and I plan on keeping the Medium in the event I need the extra space or they shrink during washing.

For reference, I am 5'0", 135 Ibs, 39" - Bust, 30" Waist, and 39" Hip.

I have included a photo reference to show just how close the sizing is (flat, on the ground) when comparing the medium (M) and small (S) - the M is below the S in the photo. If you are in between sizes, you may want to size down!
