These are pretty and made better than the price would indicate. I usually favor a similar style from a pricier, well known brand. These are comparable to the string bikinis from the mall standby, but with thicker fabric, less give, and yes, they certainly do run smaller. I ordered up a size and they work fine. I wouldn't pair them with lightweight or close fitting pants, though, as due to the style, visible line would be likely. Also, your monitor may vary, but the picture for me makes them look pastel in color, and that is certainly not the case. The colors are all bold, which is great by me.
