I'm happy to say that I've found yet another clothing store that is new to me and that supports prim breast users: Renee India.
At Renee India you will find mesh shoes, and you will also find prim breast-friendly clothing ranging from some items I'm too timid to wear to informal outfits and dresses to some lovely formalwear. When I can, I will buy their "Retro Maxi" gown, not to mention some really pretty fuschia mesh boots.
Do check Renee India out. (I hasten to add that they should not be confused with an engineering company that is actually in India. Renee India can be found in SL Marketplace, and the inworld store is at Mayotte (47. 62. 31)).
