Stunner from beach almost bares everything initially (4)
I believe the answer is:
babe
'stunner' is the definition.
(I've seen this before)
'beach almost bares everything initially' is the wordplay.
'initially' suggests taking the first letters.
The initial letters of 'beach almost bares everything' is 'BABE'.
'from' acts as a link.
(Other definitions for babe that I've seen before include "Tiny child" , "A literary newborn, or a modern good-looking woman" , "baby" , "Pretty Woman" , "Tiny infant or good-looking girl" .)
