I've found a lovely white cotton dress but it's made of the kind of material that you wear over a bikini or similar and would sure underwear. I want to wear as a dress so thought about getting a slip to go under it. What colour do I wear to make the slip (and underwear under!) invisible? Not sure if I need white or one closer to skin colour.
Have looked at this one:

Any other advice on slips under dresses welcome!!
