Let's see if someone who wears Love 15 and Perlee XS can weigh in, I know we have some members who wear that size. I wear Love 16 and Perlee XS, so my opinion would just be conjecture.
For sizing, Perlee d'or is slightly more round compared to the Clovers with diamonds. I have never tried the Perlee signature, so I can't speak to that one but it looks slightly more oval as well.
@EpiFanatic may be able to weigh in. She has a wrist about your size and I know she has the Perlee signature and the Perlee single row.
