For perfume, there’s one rule: don’t wear any. You never know if your favorite scent – even if you are convinced it’s the lightest, most perfect fragrance on earth – will cause an allergic reaction in your future employer. The only way to smell for a job interview is clean, which really means no noticeable smell at all. Now, that said, there is one exception to this rule – if you are interviewing for a company that produces perfume! In that case, feel free to wear a product created by that company, but do put it on in small doses. A little goes a long way!
