I've just gone back to work after maternity leave, and I usually wear skirts with opaque black tights. Now either my body shape has changed (likely, but the old clothes still fight, so can't be that much) or tights manufacturing has changed in the year or so I've been away. The legs are fine, but the bit from top of legs to waist seems too short and they feel like they're constantly falling down. Anybody recommend any black tights with a long belly covering bit? Don't mind if they go up to my chest, I'd rather that than where they are right now. Tall ranges won't work as I have quite short legs for my height. For the record, 5ft6, size 12.
