Are there any online stores offering discounts on women’s formal dresses?

I visited a clothing shop to buy women formal dresses two days ago I wanted good price I wanted nice fit I wanted simple elegant look but I got confused fast Some dresses look very fancy but price was high Some feel soft but not very formal Some colors are nice but size was not right I try one dress and it looked okay but not perfect for event I could not trust them I could not decide confidently

Then I visited another shop in the same area Some formal dresses had small discount Some had seasonal sale Some looked new collection but still costly I asked worker and she said online stores give more discounts than physical shops I remembered one dress I bought before that looked perfect in shop but felt little tight in party That made me hesitate even more I kept thinking maybe online is better but also risky for size and fabric

To check more variety and options while scrolling many online marketplaces including alibaba I saw many women formal dresses with discounts Some had flash sale Some had coupon deals Some had bundle offers Some had free shipping I is thinking maybe online gives more saving but choice is too many This made me excited but also confused again Now I am thinking brands like Zara H&M ASOS Shein and Mango often give better online discounts during sale season I think online is best for deals but still I am not fully suer which store gives real best formal dress discount with good quality what would you choose for party dress shopping online or store?
