What to Wear in Melbourne in October

Dress for the gate, the grass and the sky, in that order. The Bureau of Meteorology's Olympic Park figures put October at 20.5°C in the afternoon and 10.9°C at dawn, with 64mm of rain over about 9 days, and on BoM's long record for the old city site no month is wetter. That weather lands on racing Saturdays: Turnbull Stakes Day on the 3rd, the 150th Caulfield Cup on the 17th, the Cox Plate at Flemington on the 24th and Derby Day on the 31st. The members' enclosure turns away short playsuits, shorts above the knee and anything that shows your navel. The lawn swallows a stiletto. UV sits at 3 or above all month. So: a trench over a midi slip dress, flat leather shoes, and an umbrella.

The capsule

1. 
   01

   Camel belted trench, navy packable layer folded beside it

   Pack it for the showers and wear it through the members' gate. On BoM's long record for the old city site October is Melbourne's wettest month, and a belted camel trench closes over a slip dress without breaking a line of the VRC's code. Belt it at 11°C / 52°F on the way out, carry it at 21°C / 70°F, and keep the folded navy layer for the evening.

2. 
   02

   Oat linen blazer, single-breasted, notch lapels

   A single-breasted oat linen blazer squares off the slip dress for the members' enclosure and covers bare shoulders in a month when Victoria's UV sits at 3 or above. Linen breathes at 21°C / 70°F where wool would not, and it holds its shape worn open from the Cox Plate's 12:25pm first race to the 5:50pm last.

3. 
   03

   Oat thin V-neck cardigan

   From 4 October you need an evening layer. Daylight saving moves sunset from about half past six to about half past seven, so the walk to dinner after the last race happens outdoors in the cooling hour. A thin oat V-neck cardigan goes over the slip dress or under the trench, and it folds flat into the burgundy bag.

4. 
   04

   Deep navy silk-satin midi slip dress, bias cut

   Nothing in a navy midi slip dress trips the Victoria Racing Club's members' code, which turns away short playsuits, shorts above the knee and anything that shows the navel. Bias-cut silk-satin moves with the 3pm wind on the lawn, and deep navy holds its colour in hard spring light. Blazer over it at the gate, cardigan over it after dark.

5. 
   05

   Cream wide-leg tailored trousers

   Tailoring is how Melbourne dresses for work, and cream wide-leg trousers are the spring-weight version: under the camel trench in the CBD at nine, with the cardigan for a Fringe show at Trades Hall in Carlton, which runs until 18 October. The wide leg falls straight over a ballet flat, and on Derby Day, 31 October, cream stands in for the white half of the monochrome theme.

6. 
   06

   Dark brown leather ballet flats, bow trim

   Stilettos sink into grass, and Flemington's lawn is where you spend the gaps between races. Dark brown leather ballet flats stay on top of the turf, cover the walk from the gate to the stands, and are closed leather shoes on a course whose members' code bans thongs, gumboots and joggers. Brown, not black, sits between the camel and the burgundy.

7. 
   07

   Burgundy structured top-handle bag, crossbody strap, gold clasp

   Carry it by the handle through the members' enclosure and on the strap in the crowd at the 5:50pm last race. A structured burgundy bag with a gold turn-lock shuts tight when a shower crosses the course, holds a phone, a card and sunscreen, and is the one saturated colour against navy, oat, camel and cream. Leave it at home on Derby Day, when the theme is black and white.

8. 
   08

   Black compact umbrella

   About nine days in October bring 1mm or more at Olympic Park, and a shower does not wait for the gap between races. A black compact umbrella folds small enough to carry from the first race to the last, leaves the trench free to stay over your arm, and is the one accessory here that also suits Derby Day's black-and-white theme on the 31st.

A suggested look — deep navy silk midi slip dress, oat linen blazer, dark brown leather ballet flats, burgundy top-handle bag, camel trench.

What to avoid

• Stilettos on race day — a thin heel sinks into Flemington's turf
• Short playsuits, shorts above the knee or a bare navel in the members' — the VRC turns them away
• A cap or visor for sun — the Victorian Department of Education rates both unsuitable
• Leaving the trench behind on a bright morning — October is the wettest month on BoM's long record
• A linen-only evening after 4 October — sunset moves past seven
