I wouldn't say I look polished, as polished isn't the look I'm going for. I've never really been the Ralph Lauren type, and it's not something that suits me/my coloring/my features. But I do look good and feel confident.
My basic mood is fun-not-fussy. Fussiness is the worst.
Hair:
Flattering cut. I have crazy curls everywhere and have learned to embrace. Rarely shampoo, use excellent conditioner, and air dry.
Face:
Very simple makeup routine.
-Serum with SPF
-While that dries, couple slicks of mascara
-I have striking natural eyebrows. I just use a little Boybrow by Glossier.
-BB cream, again with SPF, rubbed in with fingers to even skin tone
-Slice of highlighter on cheekbones and nose
-Tinted lip balm if I want it
Literally takes 2-3 minutes. I still look like me, and bonus that the SPF helps with long-term skin. A huge amount of makeup takes way too much time and 9 times out of 10 makes the person look worse not better.
Clothes:
I have a kind of uniform that I wear most spring/summer days: slim black pants; well-fitting soft t-shirts in black, blue, green, or garnet; cardigan in either black/grey or jewel tones.
I wear good flats (I've been enjoying Rothys recently) and have a fantastic, posh-but-slightly-boho purse.
Absolutely nothing with frills, flounces, open shoulders, etc. Clothes don't have to be fancy (many of my best shirts come from Target), but they also shouldn't be flimsy. Cheap material holds stains and wrinkles and looks shabby quickly.
I have a go-to 8-10 pieces, making getting dressed super easy.
Accessories:
Nothing looks less polished than fussiness.
I often wear simple jewelry with a hint of funk (so, plain faux-diamond studs, but a little too big, or clean-line ear cuffs).
My go-to for jewelry is bauble bar. Some of their stuff is OTT, but it's at a really good price point and has a bit of cheek to it. You can go OTT if you have the confidence to pull it off.
For all that's holy do not wear anything heartshaped/Pandora-ed (or similar mood) unless it's ironic.
Nails:
Essie nail polish on very short nails in interesting, usually dark colors (eggplant, forest green, garnet, smoke grey, rose gold).
Person:
I try to give myself 15-30 minutes a day for myself. I have slightly decadent baths. Occasionally use a face mask when otherwise watching tv/hanging around the house. I exfoliate 1-2 times a week, which my skin needs. I drink a decent amount of water.
Also key: I have a lot of fun. I laugh a lot, I spend time with people I love, I have an occasional drink, I read things that interest me, I keep up with pop culture and politics. I know it sounds ridiculous, but when I don't do these things, my face seems less...alive.
