For the Office. You can make tweed blazer more youthful by pairing it with a ladylike graphic tee.  Here, I also added a colorful skirt, but you could go for basic black or the matching tweed skirt.  (This is not the exact blazer I would pick. I would have loved something a bit more Chanel-like (collarless, slightly boxy cut), but sometimes the Polyvore gods just aren’t in a giving mood.)

I like this look for a Casual Monday on Capitol Hill.  But you could wear it to a lot of work environments, esp. with the jacket, which could be easily buttoned up before meetings to conceal the tee, if need be.  Then, take off the jacket and wear it to the bar with friends.

I added pearl jewelry because if you’re going to wear a graphic tee, everything else needs to be really ladylike.  Same advice goes for the d’orsay kitten heels.  The coral clutch from Reiss is also extremely feminine in a prim and proper sort of way, but the color makes it a bit more modern.

For the hair, I would definitely wear mine up in a French twist or a wavy, twisted updo.  For the makeup, I would choose a barely-there red lip (think Fresh lip treatment‘s kiss of color) and a lightly rosy cheek and subtle, winged eyeliner. 

For Casual Friday.  With bright yellows and bold greens, this outfit is definitely a spring/summer combination.  I like the flirty skirt and proper cardi with the tee.  It says, “Yes, I’m girly, but I have a sense of humor about it.”

To accessorize this combination, I added a yellow stone statement necklace from Kate Spade.  I also adore these little bee earrings from Alex Monroe.  They’re just so charming. 

I paired this look with a basic crossbody bag in a neutral tan.  I also added a cognac sandal, which would be fine for my office, but may not be fine for yours.  If that’s the case, try a gold or neutral ballet flat. 

For the hair, I would wear it down.  If you’re under the age of 25, try a thin, gold headband.  For the makeup, pink cheeks, defined brows (bright colors require defined brows) and greige nails.
