I was planning on wearing the 2L because I'm a little larger in the chest (32c), but the 2L was about an inch too long even with 4 inch heels and I'm 5'8''. I went with the 0L and it was practically a perfect length for the 4 inch heels. The bust was tight when I first put the dress on, and I had to pull my breasts across when I was zipping it, but that didn't bother me the rest of the evening. If you are taller but wanting to wear sandals, I would order a regular length.
