Sadly dowdiest having multiple aspects (3-5)

I believe the answer is:

two-sided

I'm a little stuck... Click here to teach me more about this clue!

'having multiple aspects' is the definition.
I can't judge whether this defines the answer.

'sadly dowdiest' is the wordplay.
'sadly' indicates an anagram.
'dowdiest' with letters rearranged gives 'TWO-SIDED'.

Can you help me to learn more?

(Other definitions for two-sided that I've seen before include "covering both opinions" , "Double-faced" , "Having a pair of aspects" .)

I've seen this clue in The Telegraph.
