Antaeus is really hard to wear in hot weather. I've got a bottle but rarely do I reach for it. It is somewhat cloying for a while but once it dries down it gets really smooth. Prob is in our hot weather even at night, the moment I sweat Antaeus comes back with a vengeance. 

Egoiste is perfect for the office as its not very agressive but at the same time its distinctive. I didn't like it at first but after a few wearings it became one of those frags that I use when I can't think of anything else to wear.

Yes I admit that XS does give off that cheapo deodorant vibe. What to do it came out around the time of Eternity n Platinum Egoiste. So all the deos tend to have that smell. XS is another one perfect for the office as it is fresh n light but has decent sillage n longevity without going overboard.

Citrusy n sweet = most common type of frag in the market...even beats aquatics. give Solo Loewe a try as I feel it is one of the best n most versatile frags out there. Davidoff Silver Shadow Altitude, Hermes Concentre d'Orange Verte and Clinique Happy for Men are among the better citrusy frags out there. But as usual these citrus based frags tend to be short lasting with light sillage. Though Solo Loewe ain't exactly a citrusy frag.

Also did u try Chanel Pour Monsieur ? it has an old man vibe to it but it can work well for the office. CPM is my frag of choice for formal occasions where scent needs to be politely discreet. other than CPM... Dunhill Edition, Versace The Dreamer, Prada Infusion d'Homme, Mugler Cologne and a few more r my staple frags for work.
BTW, did u spot YSL and Guerlain counters at Sogo ?

I like your taste in frags man. Do try Hermes Hiris...its one of the best light female frags IMHO.

Which Guerlain u tried ?

Some counters have Ice Men, B*Men, Pure Malt n Pure Coffee. Or just ask the SA coz they might not display the frags but the testers might still be available (eg Mugler Cologne).

Tried lolita lempicka au masculin the other day and i love it
