One example of these is Saree Swarg, which has outfits from around £60 and upwards, and look quite affordable and similar to the prices on the high street, and has a fair good range of designs. I've posted a few pictures of their designs here to get an idea, they're not extravagant designs, but pretty, colourful and very wearable. My favourite design which has caught my eye is the first one, which is around £80 for the suit. Although this dress doesn't have a lot of embellishment, I love the colours used and the rich fabrics, and I can imagine this would make great party piece and the fact that it looks so dressy without needing much effort.
There are a lot of the more simpler designs and more classic designs, which suggest value for money, but this may not appeal to everyone who may want something more fashionable. In any case, have a browse, if anything, it may be a source of inspiration!
