Went to Seoul with some friends and the women in our group went to two different places for their color analysis. My buddy and I (both men) thought it sounded interesting but couldn't book a reservation at either place so we found Studio Bomnal on Google Maps. When we arrived, the staff was extremely courteous and welcoming. Our appointment was with Kaya, who was friendly, spoke great English, and explained everything clearly (we even introduced a new word to her: understated). We learned all about the seasons and color theory. The draping session was super fun! Consider doing this as a group activity since your friends can react alongside you. We had great personalized recommendations (on paper and in PDF). I suggest doing this earlier in your trip so you have helpful tips for shopping in Korea!
