Ok, I think I'm maybe back down to my normal weight post DS2. I have three pairs of trousers I bought before they fit, which I like. But they are low-rise. Not scary low-rise, but still. I need to wear long shirts with them. And they go lower as I wear them. Without much sitting on the floor etc, I have visible butt cleavage. I do not want visible butt cleavage.
So do I have to stick to high-waisted trousers? Is there any way to tell (particularly online) if trousers will fit well and not do the weird gappy thing in the small of my back? These trousers do it even more than normal trousers. I don't think they'd take a belt, really.
(I am a 16 or so.)
