Lea You mean uniforms in general have advantages, or you mean the full slip and blazer have advantages over skirt+blouse+tie? And in either case, which? (Apart from turning on some of the members here 😉 )
Daphne I do want to know what you all think
I think you really want to go for the strictest option, and are just looking for confirmation. But knowing nothing about how you look like, what your social environment is, what kind of work you are thinking of, we don't have anything to base serious advice on. (And like Angelina said, you shouldn't divulge enough information so that we could.)
