EVEN after the working week is over, many executives may find themselves catching up in the ''office'' at home. However, the weekend worker may like to have a very different environment in his study or den - revealing a more personal touch in the accessories adorning the alternative workplace. Photographic records of meetings with presidents and princes or, more usually, family portraits, can be displayed in marquetry inlaid picture frames for individual prints. A multiple photo frame can also be portable, as with folding English leather pocket models. They range between $150 and $300 from Nugget in Prince's Building. Pig-skin leather frames from the Polo Ralph Lauren boutique co-ordinate with leather key fobs, wallets and purses, although a crocodile-skin wallet at $4,000 may be more appropriate for city executives. Pride of place in a club-type study could be claimed by the inlaid wooden cigar box from Hermes. Incorporating a humidity gauge and regulator, it sells at $8,100 and is the ideal receptacle for the finest Havanas. Home working over, thoughts turn to getting away from it all. The Polo range of accessories fits the bill, with golf, tennis, skiing and even hunting being catered for. Each sport has its own theme collection, with the logo being prominently displayed on shirts and sweaters. Staff at Ralph Lauren can provide customers with a complete, co-ordinated outfit on request, offering what shop manager Christina Shu calls ''total lifestyle'' clothing - from cap to socks and even a leather-covered hip flask for those cold winter days. ''Silk ties, bow ties and cravats with sporting logos are popular items, particularly with tourists from Japan and Taiwan,'' said Ms Shu. Silk scarves with spots, stripes or teddy bears and braces, practical as well as colourful, are other favourites. Rocking horses, flying horses, turtles and fish adorn the Hermes range of ties, which are among the most popular accessories. ''Our designs change each year, so people know they will find something new,'' said sales assistant Ida Chan. ''Also the ties with geometric patterns and belts with the trademark ''H'' buckle are leading items.'' Japanese tourists are again regular customers at Hermes, although not all year round. ''After Christmas we have many visitors from Japan, since they have a long holiday break then,'' says Ms Chan. Bigger, bolder patterns stand out on the Italian ties of Trussardi, slightly cheaper at $450 - $650. The store also carries a range of hunting caps for those outdoor rambles on winter days, and an extensive range of bags to carry everything ''away from it all.'' Ralph Lauren's extensive collection of bags covers the spectrum from the handy leather Boston bag bearing their Karabu label to a range comprising suitcases through to wallets in a Black Watch tartan. The sporting collection also offers readily identifiable bags for tennis or skiing accessories and soft fleecy lined shoulder bags for general purpose use.
