6d fashionable colour scheme, er, shows lack of delicacy (9) - *N*E*O*U* - is it 'indercorus', although incorrectly spelt? 23a extra weight fish (4) - *I*E - is it pike? if both correct - why?
As there's no reply, but hoping I'm not stealing anyone else's thunder.
In = fashionable decor = colour scheme er = um (both hesitations)
A wide in cricket is called an extra. w = weight and ide is a fish.
