So basically I saw an email from Shopbop promoting a 25% off code you'll be able to apply on styles which are already on sale in the Designer Boutique section. I have found some red dresses on the first page (for Valentine's I guess), i.e:
* Loyd/Ford Sleeveless Lace Dress in sizes 6 or 8 is reduced to $314.84 (from $1,049.47) - now $236.13 after the promo code
* Loyd/Ford Jersey Maxi Dress in sizes 6 and 8 is reduced to $227.39 (from $757.95) - now $170.54 after the promo code
* Marchesa Notte Sleeveless Lace Cocktail Dress in sizes 8 and 10 is reduced to $579.40 (from $1,158.79) - now $434.55 after the promo code
* or get a pair of red heels by Guiseppe Zanotti for $325.23 (was reduced to $433.64 from $867.27), only sizes 40.5 and 41 are in stock
I really liked the Marchesa Notte dress above, which is also available in white/gold for even less at $347.64 in sizes 8 and 10. Apply the promo code to this one and suddenly you're only paying $260.73 for a dress which originally would have cost you over $1,100 pre-sale.
If you also like the style, check out other Marchesa Notte dresses on sale in the category as you'll be able to save roughly the same on all of these styles - which is about 80% off or in other words $900 off their original prices.
