Medela Purelan Lanolin

I prefer the Medela brand lanolin. It's a little more liquid-like but still gives a lot of relief. I have also tried the Earth Mama stuff, which I found smells great but is a little...greasier? I sometimes use it on the inside part of pump flanges where my nipples rub.

Lansinoh Lanolin and Medela Tender Care were my favorites. Plus either a gel cold or completely braless always helped.

Lanolin from Medela. You can also wear it while breastfeeding, it's like lip balm, baby doesn't mind.

It doesn't matter whether you wear a shirt or not. I found the lanisoh one very sticky and preferred medela, but any lanolin based cream will stain your clothes. You don't have to wash it off before feeding baby. Personally I went without a top and just wore an unbuttoned flannel as anything touching me was painful. I preferred silverettes too. If the pain doesn't start to improve then I'd say get baby's latch looked at.
