, maybe with a touch of silk and...

[azz]

a. Her blouse will be linen, maybe with a touch of silk and golden buttons.
b. Her blouse will be linen, maybe with a touch of silk, and golden buttons.

c. Her blouse will be linen, maybe with a touch of silk with golden buttons.
d. Her blouse will be linen, maybe with a touch of silk, with golden buttons.

In which cases does the 'maybe' only modify 'a touch of silk', and in which cases does it modify the 'golden buttons' as well?

 

[Lwords]

In all four examples, "maybe" is most naturally read as modifying only "a touch of silk." The golden buttons are stated as a definite feature, not an optional one. If you want "maybe" to also apply to the golden buttons, you should repeat it: "maybe with a touch of silk, maybe with golden buttons." As written, "maybe" does not modify the buttons.

Not a teacher.

 

[probus]

To me maybe is a conjunction, not a modifier but I'm no grammarrian.

a. Her blouse will be linen, maybe with a touch of silk and golden buttons.
b. Her blouse will be linen, maybe with a touch of silk, and golden buttons.

c. Her blouse will be linen, maybe with a touch of silk with golden buttons.
d. Her blouse will be linen, maybe with a touch of silk, with golden buttons.

a is fine. I consider maybe to be an adverb. it precedes with and therefore, in my opinion, modifies both a touch of silk and golden buttons.
b does not work - it suggests that the blouse will be linen and golden buttons (maybe with a touch of silk).
c suggests that the silk has golden buttons.
d is fine.
