A stylish and utilitarian Mondaine watch is not a luxury watch, but a necessity. No outfit, formal, semi formal, or casual, is not complete without a Mondaine watch.
At other times, it could be dry cleaning or steam ironing which is required for a certain set of clothes. This can happen with formal suits et al. Make a separate pile for these as well. Again, take out time to organize the work to be done for these. Dry cleaning will add a new chutzpah to the clothes. It is highly recommended especially for certain articles. Sometimes, colored clothes get stains on them when you wash them. They give a smudged look. Sort these out too. Make a category for these clothes which you need to get bleached.
