They can give you a better line. I have a couple of waist slips in the drawer one black from John Lewis and a bright red one, which I can’t remember where it came from; they last for ever. The red one is fun to add that possible quick splash of colour.



I’m not a regular slip wearer though and reserve them for certain skirts that tend to cling to (my) bumpy bits and even then not always.



I’m less bothered about skirts/dresses being slightly see through in the summer, within reason. The silhouette is fine by me. As long as if’s not for work.
