Don't feel like wearing pants or a skirt, but you still need to look put together? Take a cue from Vanessa Lachey and rock a flannel dress. It looks like you tried this morning, even if you actually didn't at all (aka you just threw this on as you were walking out of your apartment). Here is a recreation of Vanessa's casual fall style for much less.
A flannel dress is a great piece for transitioning your wardrobe from summer to fall. The dress form will keep you cool during the day and the flannel fabric will keep you warm during cooler nights.
Continue the western and boho chic vibe with fringed booties. Look for a pair of heeled booties if you want to dress up your outfit a little bit. If you want to keep it casual or you have to walk a lot, go for a pair of flat booties.
Maybe you didn't have time to take a shower this morning? No worries, throw a hat on your second-day hair, and no one will notice. Protect your eyes from the glare with a pair of aviator sunglasses. Grab an oversized tote to carry all of your essentials and you are good to go!
