Girl's garments? (5)
I believe the answer is:
jeans
'girl's garments?' is the definition.
'jeans' can be an answer for 'garments?' (jean is a kind of garment). I am not sure about the 'girl's' bit.
'girl's garments?' is the wordplay.
'girl' becomes 'Jean'.
'garments?' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'jean'+'s'='JEANS'
Can you help me to learn more?
(Other definitions for jeans that I've seen before include "boys in France?" , "Are they worn by girls in Britian" , "Strides casually" , "Trousers made of strong cotton, usually dyed blue" , "Denim trousers" .)
