Hi, I have this one in gender neutral colours. Not sure on size, it was either "medium-large or large). I measured it and the rise (front of waist to back of waist) is 19", waist 18", thigh 10". Fleece soakers tend to be sized by inches rather than weight guides.
Looking for £6 inc postage. EUC (used twice? I don't even have any fitteds anymore but when I did I mostly used Motherease wraps, bought this for DD and her skinny thighs never filled it!).
