Colloquial — describes things (clothes, restaurants, gifts, decor) that look expensive or sophisticated. Often heard with
显得 (xiǎnde, to appear) or in the negative
不上档次 (déclassé). Compare with
高档 (gāodàng, high-end), which is purely descriptive;
上档次 has a stronger 'gives off the vibe of class' nuance.
