Venirle de perlas

[poli]

Example:El parque le viene de perlas cuaquiera que busca sombra en un día cálido.
I think it means to be convenient, and I would like to know if I'm correct and if the term is commonly understood.

Look here for "caer como anillo al dedo" which means practically the same.

Thanks. I think: "works like a charm" or "to be just the thing" may be good
English translations.

I agree. (Although I believe "de perlas" may become a bit dated soon...)
Other options (I believe there are many)
ir de perlas = come up + a treat, work + a treat, go down + a treat.
salir de perlas = come up + a treat, go down + a treat.

Oxford also gives good options,
de perlas (fam) great (colloq);
el negocio marcha de perlas = business is great [or] is going really well;
el viernes me vendría de perlas = Friday would be great for me [or] would suit me down to the ground;
todo salió de perlas = everything went perfectly, everything turned out fine (colloq)
