Relax one familiar outfit deliberately
Take a combination you enjoy wearing during the week and change one piece. With fabric trousers and a shirt, you might leave off the more formal jacket. With a blazer and trousers, replace the shirt with a plain T-shirt. Changing the trousers, shoes and top all at once makes it harder to see what creates the difference you wanted.
Check the result while sitting. A T-shirt can fall differently beneath an open jacket because its fabric may catch against the lining more than a shirt does. Take the jacket off and put it back on. The combination should work without lengthy adjustments.
Relaxed clothes still need to serve a working day
Comfortable jeans are useful if you can sit in them for several hours. Strongly frayed or very wide pieces are style choices, not requirements for a less formal day. Your existing straight jeans can do the same job.
Actual use is more helpful than a label when choosing shoes, too. A clean, familiar pair for the commute often makes more sense than new shoes bought simply because they seem casual. With long trousers, check whether the hem still clears the ground with a different sole height.
Think about the evening
If you have plans after work, avoid carrying an entire second outfit where possible. Changing the outer layer or removing the blazer may be enough. Use a bag with real space for the garment you will take off.
After a successful Friday, record the combination that worked. A photograph or a few words is sufficient. This builds a small selection of wearable versions of your own, rather than making every Friday another search for a supposedly correct uniform.
