Your products are definitely on the very high end of price when it comes to clothing. Do people buy expensive clothes from a brand they've never heard of online? Maybe you're better suited to a bricks and mortar store so people can touch and feel the product, without the heft of a well known brand behind you. If not a store, then supplying other stores.
The discounting strikes me with cognitive dissonance. You're trying to sell a premium product - why would you discount? Personally I'd never buy clothes that were this expensive outside of a premium suit. I am a purchaser of other premium products, though. Look at what the brands you want to imitate do. Do they discount? Do they do run out sales? Better to just change your price if you didn't pick the right one. If someone's looking for a discount, they're probably after a $20 sweater, not s $500 one.
