As long as you prep your base layer (Id recommend merino-wool leggings, plus a long-sleeved thermal top), you can get away with clothes that might initially seem summery
If you wear specs, choose a frame that gives you a professional look
The subtle elegance of nude heels beautifully contrasts with the boldness of a black dress, maintaining a sophisticated balance
Garment details: A high neck, open back maxi dress with an elasticated waist and cross over detail on the back
For the sleeves, you can turn them up 1/2 an inch, press, and sew with a zig zag, double needle, or stretch stitch
As a general rule, you should select accessories and accents that complement your sense of style without being either too formal or too casual
