Summer outfits for work

[gyi3]

Need smart-casual outfits for work for warmer weather.
I'm so fussy and self-conscious that I'm finding it really difficult to find what to wear to the office in the summer (I'm in a medical professional role).
I thought about midi dresses but I have skinny legs/ankles (not to mention very pale although I do have gradual tanner that I'm going to building into my routine) and very skinny/bony/veiny feet. I hate my toes so sandles are a no go too
Help!!!
Early 30s. Size 8. 5'6. Long thin arms and flat chested

Would pale colour linen trousers work? Breathable and comfortable in hot (perhaps!) weather, but with a smart cut.

e.g.

Backless or slingback flat mules/loafers instead of sandals?

Pencil skirts and loose shirts tucked in.

Reiss is a great shout, endless decent workwear options. What about loafers or ballet pumps?

Ballet pumps are a nightmare if you are on your feet all day. Do you have to wear closed shoes ? If not fitflops would be my go to choice

Not sure whether to suggest Studio Nicholson. Brilliant shapes, wonderful fabrics. They’re what I’d choose in your position - and I find I reach for the clothes I have from them more than almost anything else. They’re not fast fashion, most things will last. And they have excellent sales.

Also, I’d say a judicious mixture of Margaret Howell and Uniqlo might be practical and satisfactory. Both wonderfully simple and hard wearing - just different price points because of design structure, employment practices and fabric sourcing.

(I don’t find the middle ground between these two a rewarding place to shop. 🤷🏽‍♀️)

Thank you all for your suggestions. Very helpful!

Do you think these shoes would be ok?
