Elaborate dress that changes skin glow (4,4)

'changes skin glow' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'elaborate dress' is the wordplay.
I cannot quite understand how this works, but
'dress' could be 'gown' (gown is a kind of dress) and 'gown' is located in the answer.
The remaining letters 'silk' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'that' is the link.

Can you help me to learn more?
