There is very little in my wardrobe that transcends all 4 seasons in my climate so an essentials list for spring/summer is different from fall/winter and to be honest I don't want to think about fall/winter dressing right now as the snow falls outside! so that list will have to be considered another day.

Birks and slip-on sneaks in light neutrals
Joggers in cotton, linen or blend - grey, blue
All cotton or linen 3/4 sleeve and short sleeve tops in white, blue and grey
Cotton shorts with 6-inch inseam cuffed once in pinks and blues (favourite ones from Gap not shown)
Sweatshirt or hoodie in grey, cream or blue - solid or striped

ETA I took out pink shorts as I think they're more statement.
