A load of fashionable people in the way (8)
I believe the answer is:
shipment
'a load' is the definition.
('shipment' can be a synonym of 'load')
'fashionable people in the way' is the wordplay.
'fashionable' becomes 'hip' (I've seen this before).
'people' becomes 'men' (man is a kind of person).
'in the' means one lot of letters goes inside another.
'way' becomes 'st'.
'hip'+'men'='hipmen'
'hipmen' put into 'st' is 'SHIPMENT'.
'of' is the link.
(Other definitions for shipment that I've seen before include "Consignment of goods" , "22 [CARGO]" , "A consignment as for marine transport" , "load" .)
