If you were buying $100-$200 bras at 50% discount then you were not buying $200 bras - you were buying $50-$100 bras.
If a brand is refusing to sell $350 bra at 50% off, then it is a $350 bra. Otherwise $350 is MSRP aka the wishing price. If they do 50% off sales then it is a $175 bra. $175 makes it a premium product but not a boutique level premium. Maybe there's a market for $175 bras -- VS tried it in 2005-2007 in some markets but they did not quite sell it was dropped in 2008.
Hermes does not do sales, which is why a a Kelly 22 is $7,200 while LV Speedy is $800 and not $1,400 (Hermes does not do sales and LV does), so Hermes talks about number of units of a kind they ship while LV talks about average revenue per unit of a kind shipped.
P.S. VCs are very bad at funding apparel manufacturers. They pick the ones that they think should work which tend not to be the ones that actually work.
