A big trend in swimwear fashion from Korea is partner look. The swimsuits are often not identical but compliment each other in styles and colours. This expresses some individuality while at the same time show that you belong to your lover.
These swim clothes often come as complete sets
for men (long swim pants, shorts, swim shirt, jacket)
and women (long swim pants, shorts, bra, swim shirt, jacket).
This lets you mix and match different outfits depending where you swim.
