Itās heartening (if you can call it that) to see everyone wrestling with the same short clues which are eluding me. 13ac looks hopefully settled now, thanks to the insights here, but if anyone can shed any light on the parsing of 18ac and 22d, that would be great.
18ac I have a straightforward enough synonym for āripā but I canāt work out where āshort hem to denim outfitā comes into it, which makes me think I may have the wrong answer.
22d ādrink and drugsā I have a synonym for ādrinkā as a verb but the ādrugsā would then be a common crosswording letter for drugs with a three letter word in front of it, which if my answer is right would suggest a clue of ādrink and best drugsā. Another similar sounding word also fits which is a synonym for ādrugsā - cannabis usually - but Iāve never heard it used for ādrinkā if that makes sense.
