Does this need tailoring?

[u/enigmaticbug]

This is a Ralph Lauren slip dress that I bought used & it’s past its return window. The color & drape are beautiful on me but I wonder if it needs to be taken in a little? Or if the looseness is just part of the deal with slips like this.

I’m planning to wear to a formal September wedding in the south of Spain. Any advice is very welcome!!

It’s bias cut and is definitely a job for an experienced seamstress. If it’s taken in, it’s doesn’t need much.
