For basics, Biscote offers great work and weekend wear blending the dress for work and casual weekend wardrobe into one and with its current sale of 50% OFF all marked prices, Biscote is definitely worth a look.
Biscote have a range of tops, shirts, dresses, skirts and pants, as well as knitwear and jackets and vests.
My pick: The Self Stripe Single Breasted Jacket Style Number 7C1014J-YD looks great for work. Available in black or dark grey and priced at $95 before the 50% discount I think represents great value. Match this up with the Self Stripe Classic Boot Cut Pant also available in black or dark grey and priced at $75 again before the 50% discount and you've got yourself a very stylish and inexpensive suit for work.
I also like the Viscose/Spandex lace trim camisoles that are in the new arrivals section. In particular, I like Styles 7C1033T and 7C1049T camisoles as shown in the pictures below. Both are available in either black, blue, chocolate or ecru. Style 7C1033T is priced at $25 and Style 7C1049T at $30 and that's before the 50% discount :)
The Biscote sale is worth a visit but note that this is a limited time only sale.
