Amber Riley has launched a plus-sized clothing boutique.

The 'Glee' actress and her sister Ashley have set up a website called Rileyland Fashions to sell one-off pieces to flatter curvy figures after realising fans were clamouring to copy Amber's style.

The singing sensation wrote on Facebook: ''My sister and I are clothes fanatics and since so many of my curvier fans always express that they like my clothes I thought why not clean out my closet and fill up all of yours.

''The clothes are affordable and most are never worn! There will be an official website coming soon with more than one of [a] kind clothing and more sizes for you plus size cuties!''

The siblings have also set up an Instagram account to promote the dresses, tops and shoes for sale, and their efforts have paid off since stocks sold out within minutes.

Sharing an update on Instagram, Amber and Ashley wrote: ''We are sold out! We are overjoyed!!!! Thank you ladies for showing us love! We are working hard to restock RileyLand Fashions with new stuff!

''We will keep you updated. Again thank you all. For those who have ordered, we are shipping your items before the week is over. Have a good evening!''
