Your Bonsoire Prom Dress Shopping Experience

We believe that shopping for your prom dress should be relaxed, personal to you and most of all, lots of fun! 

When you arrive for your pre booked appointment, you will be greeted by your personal stylist who will discuss with you what ideas you have, your favourite aesthetics and any colours you want to try/avoid. If you have a dedicated Pinterest board for your inspired Prom looks we'd love to see it!
You and your guest will be shown to our collection areas where you can browse the dresses and choose the styles you wish to try on. Your stylist will also pull out designs they think you might like. 

Now the best part! You will try on all of the styles that you've chosen and your stylist will be on hand to offer advice or answer any questions you have. 
We'll keep your favourites to one side and whisk away the ones that don't quite hit the mark. 

When THAT dress comes along - the one that makes you want to wear it everyday forever - we'll make a note of your name and school and grant you exclusivity to the design, meaning nobody else from your school will be able to purchase the same dress from our store. Its all yours!
