A lady at work said that I was a knucklehead for buying v-neck sweaters without camisoles (what do I know about fashion). I want it to be right. What type should I buy, she mostly would wear them for casual occasions and likes the satin-type stuff. Links would be appreciated.

I like to wear a long "under" garment under blouses, long sleeve shirts, because I don't like when shirts ride up. I prefer a stretch or lycra or similar material

For bustier girls with small frames. I would like ones that are longer in the torso. Large sizes fit my bust but not my frame and they are too baggy. Where could I find well fitting camisoles?

Not the normal colors
