Parisian here.
1. Which part of Europe? Urban or country? We’re not one country, you know. Some provincial areas are more conservative, the south of Europe may be more climate-friendly for your wardrobe, and big cities, particularly Paris, always love dark solid colors.
2. Wear what you want, within limits of climate and decency.
3. If you want a job, not in an artsy folksy community, you’ll have to tone it down a bit.
4. Sorry to mention it, but of course part of looking good in France, and especially Paris, means being slender. You could wear a trash bag and heels and walk down the rue de Rivoli in a jaunty fashion and be thought to look good... if you’re slim and carry yourself well. Overall weight perceptions in Europe are not as skewed as in the US.
4. Big smiles, friendliness and a dogged willingness to wait for the grumpy natives to accept you will go a very long way to making your stay more pleasant
