The useful split here is not brand or fabric. It is whether a piece is bought to wear often or bought for one occasion.
Everyday pieces
Volume, pace and honesty. Low start, quick runs, lots where the sizes are coherent. These build the room, and the room is what makes the occasion pieces sell.
Occasion and ethnic pieces
Fewer bidders, more questions, higher numbers. Give them time on camera, expect questions about fit and seam allowance, and use a reserve where a quiet night would cost you.
What moves the number
- Condition at the hems, underarms and lining
- Fabric and whether the composition label is readable
- Beadwork and embroidery, intact or lifting
- Whether the piece has been altered, and how much seam allowance is left
- How completely it is measured
That last one is real. Measured garments sell for more than sized ones, because a buyer who is confident bids.
Lots
Group by size, not by colour. "Four kurtas, all measured 96cm bust flat" is a lot somebody can bid on. A mixed-size bundle is a gamble, and it sells like one.
Questions people ask
Should I price ethnic wear by the work or the fabric?
Both, and say which you think is carrying the value. Buyers in this category often know more than the seller and will tell you.
Do I discount for alterations?
Only if they reduce what the piece can become. A hemmed dress with allowance left is barely affected.
Is it worth dry-cleaning before a show?
For occasion wear, often yes — and say that you did.
