Perfect without stitches? (8)
I believe the answer is:
seamless
I believe this is a double definition.
'perfect' is the first definition.
'without stitches?' is the second definition.
('stitch' can be 'seam' (seaming is a kind of stitching) so maybe 'without stitches' can be ''seamless')
(Other definitions for seamless that I've seen before include "Showing no joins" , "Showing no join" , "Unbroken" , "Of cloth, made without a join or stitches" , "Without obvious joins" .)
