ISABEL SAYS: Black seems a bit funereal for the races, and I worry about the quivering feather detail. However, I like the sense of drama it gives. Hats that sit quite far back on my head seem to suit me better, framing my hair and face. STEPHEN SAYS: Black can be very unforgiving, but the trimming on this is light and fluffy, which stops it being too harsh against the face. It looks better worn further back on the head — black cutting across the face is never flattering.
