Please note: Each style of our bridesmaid collection is individually dyed and as such, we unfortunately cannot guarantee the same colour or tone will match for different styles. This includes styles that are restocked, as there can be colour differences between productions. To avoid this, we recommend that our brides purchase their bridesmaid dresses within the same order so we can ensure they are from the same collection/batch.

"just so so so so flattering and a sexy style"
"Love the fit & material is definitely high quality! I’m currently loosing so I sized down but the 8 fit perfectly! I’d definitely recommend these dresses and I’ll be a bridesmaid this may so definitely give stars for me!"
"It was a great fit, the dress was soft and shiny. This is my 5th dress from Billy J and has never failed me."
"Lovely material, stunning colour. I upsized because I measured to be in between sizes but could have easily stuck with normal size instead"
"Amazing quality and gorgeous style highly recommend"
"Absolutely loved this dress. Colour and fit were stunning. No issues with static coming out of packaging and suitable to so many different occasions."
"Love this dress! Using it as a bridesmaid dress and the bride also loved it! Material is also made with high quality. 💯 I'll definitely buy from this store and recommend it to my friends 💚"
"Such a stunning colour and fabric, quality material and cut, fit comfortably - it runs a little larger in size but it was still the perfect dress for my best friends wedding day!"
"Comfortable dress, can’t fault"
"Beautiful fit and nice thick material. Myself and my friends ordered an 8 (bridesmaids order) but it definitely was more of a size 10 so we have all need to return it for a size 6. Would definitely order down 1 size to your usual."
