What kind of business do you want to see in the market?

I've been thinking of ideas of what kind of fashion business I should start, and I wanted some advice from different people, so I decided to talk to you guys, because you're my target audience so the best way to collect the best information is to ask you! I thought of a couple different ideas, so please leave me a comment or send me an email (To stylechoice101.gmail.com) about which of these ideas sounds best.

• 20's hairbands - Cheap but stylish 20's inspired hairbands for everyday and formal occasions.
• Designer dresses - Handmade dresses designed by me for all occasions. More expensive dresses priced at around £50 but perfect for prom, going to weddings, or cheaper dresses for everyday.
• Everyday clothes - Everyday clothes for teens aged 11-19. Only available online. Prices between £15-£30.
• Design your own dress - A website where you can use a program to design your own dress and we'll make it for you and ship it off to you. You'd have to wait around 2 weeks for the dress to be made and it will cost between £50 - £100 depending on the kind of design you asked for. You'd be able to design everyday dresses, party dresses, prom dresses and more!

So which idea sounds best? Let me know! Thank you for reading! ☺
