This is another romper I brought for my Japan trip; clearly I am a fan of the easy one-piece. The key to minimizing what you pack when traveling is taking clothes that work for both day and night. A basic black and white romper and be easily transitioned for both looks. After a day out seeing sights, all I did was swap my comfortable traipsing sneaks for party-appropriate wedges - which are dressy but still comfortable for exploring Japan the lively nightlife. I added a pendant necklace and freshened up, and that's all- I was ready to head back out of the hotel in 10 minutes.
What are your day to night tricks?
