Shopkeeper

You are a shopkeeper.  You might well be a milliner.  If so, you likely import fabrics, ribbons, lace and other items from London, as well as making clothing and accessories yourself.  But you might also run a tavern where you get to talk with locals or people passing through. 

This occupation included women as well as men, although women tended to be milliners, dressmakers, or tavern owners.  Many of the shopkeeping professions for men tended to be associated with artisans -- in other words, their craft, their skill, and their tools are a big part of what defined who they were.  This was also true for women, but it was less recognized, which helped to edge women out of a number of professions (physicians v. midwives, tailors v. dressmakers).

You might also be a free black shopkeeper, in which case you are more likely to live in New England or the Middle Colonies (if you live in Charleston, you're more likely to be an artisan, such as a blacksmith, although blacksmiths in the south were often slaves living on plantations so make sure you keep your freedom papers on your person at all times).  Check out this trades sampler from Colonial Williamsburg (now the capital of Virginia) for an idea of what you might be up to.

Regardless, you probably live in a city:  Boston, New York, Philadelphia, Charleston, or Baltimore.
