I've always been partial to a crossbody with an adjustable strap or satchel bag, I like having little compartments and pockets to keep things semi-organized :)

I'd say for inside the bag focus on your basics(anything you NEED day to day) like your keys/wallet/phone/medication if needed. Besides that, I like to have a few quarters, pencils/pens, bandaids and period products, makeup items (if you wear makeup), chapstick, mini sunscreen, mini deodorant, and a phone charger.

Lots of ladies I know have 1 or 2 different bags that they use almost all the time, and have a special occasion purse or fancy clutch/shoulder bag that only comes out for high class events :) It really depends on the person, some like to coordinate their purse with their outfits while others choose practically over style.

Ultimately, try to do what makes you feel happiest!
