Dear Southern Hemisphere SYSter,
Yes, you follow after the Northern Hemisphere trends. So our fall trends will become your fall trends for 2017. When you are a member, you will notice I leave up the Big Fall Preview & Big Spring Preview so if you are in the opposite hemisphere you can use these extremely handy style guides for the season you are currently in.
Regarding the swimsuit guide, yes you save the guide and use is when your warm season rolls around (which for you, is right now).
Happy New Year, Happy New Style! Love, Leslie MSP
