This Japanese-language article explains what to wear on TOEIC test day and for the ID photo on the admit card, concluding that casual clothes are fine for both and that easy-to-adjust layers help with venue temperatures. People land on it from searches like 'toeic 証明写真 服装' because they are worried about dress rules, especially first-time test takers.
Japanese-speaking TOEIC test takers, mainly students and working adults, many of them first-timers, looking for practical test-day and photo guidance.
A mention would suit TOEIC study tools and English-learning services such as apps, online English lessons or score-boost courses, and also practical items like layering clothes, cardigans, stoles or lap blankets, or ID photo and photo-booth services. It would read most naturally near the 'TOEICスコアを伸ばしたい方へ' section, after the clothing advice, or beside the ID photo section for photo and business-attire products; unrelated brands would fit poorly.
