Making a slouchy and lazy look not so well... sloppy.
Oftentimes pairing oversized pieces and simply unbraiding your hair and leaving it down will give you a frumpy, disheveled look.
Im strategic when I play with loose fitting pieces to make sure not to
fall in that category.
I find the "perfect" half tuck shirt is long in the front and back. I tuck it towards one side rather than in the middle of my body. I roll the front of loose shorts high and leave the back long. Adding modern statement jewelry and classic shoes and handbag add some polish to the otherwise not so polished look.
I rarely curl my hair with a hot tool for a daytime look.
Its just too time consuming and fussy.
My trick for a non fussy, natural curl, is braiding clean, air dried hair and sleeping in it. In the morning I let it down and spray my favorite scrunching spray, which I also used in this video. Blow out the bangs and let the rest be.
