Park Min-Young in What's Wrong With Secretary Kim or in Her Private Life.

Kim Seo-hyung's Jung Seo-hyun in Mine.
Seo Yea-ji's Lee La El in Eve.
Park Min-young's Sung Deok-mi in Her Private Life and WWWSK are a good lw budget.
Soo-ae's Kang Yi-kyung in Glass Mask.
The trio ladies in Search:WWW.

I love office fashion in kdramas! Even though some of the stuff would never pass muster in an office where I live or is way out of budget. Some recs -
1. Lee Da-hee in Search:WWW and The Beauty Inside
2. Son Ye-jin in CLOY and Thirty-Nine
3. Jeon Yeo-been in Vincenzo
4. Song Hye-kyo in Encounter and Now, We Are Breaking Up
5. Kang Han-na in Start-up (probably the most affordable of the lot)

For fashion that is trendy, affordable and more workplace-appropriate, all the workplace romance C-dramas are also a good source.

I loved some of the looks in Vincenzo, especially in the scene where our two lawyers look like absolute rock stars getting out of the car for the trial - that pink suit was amazing, and only looked better next to Song Joong-ki's blue one!

Other ones that came to mind were Search WWW, which has lots of powerful women in powerful clothing, and Touch Your Heart/Reach of Sincerity, where the female lead has to figure out what she can wear that is appropriate for a law office, but also fun and interesting for her.

This is kind of a weird one, and I honestly don't recommend the drama itself, but I was in love with almost every outfit Nam Joo-hyuk wore in Bride of Habaek. I am pretty much always into suits, and his were fun and androgynous enough that I ended up wanting basically all of them (especially that floral one!) for myself.

Ha Ji-won in The Time we Were not in Love. (I don't recommend this for watching, just for her fashion) 🙃

I like the men’s wear in most of the dramas where they are doing ok financially as they seem to consistently get clothes that suit the season, are really well fitted and I love the range of long coats, and nice suits.

The women on the other hand have shorts, or mini skirts regardless of the weather, ridiculously high heels and random extreme fashion styling especially if they work in fashion design department. It took me ages to get that it wasn’t that Korea was obsessed with mini skirts but it was just plain sexism across the different dramas. School uniform was a prime example until they started showing the girls with tracksuit bottoms under the skirts. It’s so bad they now have a blanket or boys coat to protect their dignity when they do the obligatory piggy back ride.

Haven't seen these two being mentioned:
- Seol In Ah and Seo Hye-won in Business Proposal - I love Kim Se Jeong but her wardrobe was a little tame or too girly for my liking
- Kim Go Eun in Yumi's Cells (tbh her wardrobe is a little more accessible for the everyday employee. It's not very flashy though, compared to all the forementioned wardrobes)

Kim Nam-joo in Misty

Vincenzo for the killer suits.
Run On for the awesomely stylish yet pragmatical and comfy Seo Dan-ah.
Dali and Gamjatang, the Audrey Hepburn style sported by Kim Dali
The Red Sleeve for the most vividly colored hanboks of Yi San.

I Do, I Do (set in a fashion workplace) really stylish Kim Sun Ah leads the show

Run On (I really liked the FL's chill feminine fashion)

Her Private Life (Tailored to perfection!)

It's Okay, That's Love (Gong Hyo Jin's hipster fashion)

*Gong Hyo Jin's in Camelia's Bloom
**Kim Go Eun in Yumi's Cells
***Jung So Min's Because This is my First Life and Monthly Magazine

Kim Hye-Soo in Hyena. Her wardrobe is almost a character in and of itself, and puts the “power” in “power suit.” I love that as she rises from fly-by-night shyster to the top of one of the elite law firms, her clothes go from kinda trashy to increasingly luxurious, while still retaining their flamboyant style and eye-popping colors. Her wardrobe is the perfect expression of her “I’m here. Deal with it” personality. 🤩

Ju Ji-Hoon is a pretty snazzy dresser in this show, too, though in a (much) more understated style.

I love Chae Jung An and Ko Sung Hee's wardrobes in Suits.
Another actress who I think is elegant and smart in whatever she wears is Kwon Nara.
