Here is a round-up of Sienna Blake’s dresses in Hollyoaks that we have ID’d so far.
Sienna’s Black Lace Prom Skater Dress

Trust Sienna to wear a black dress to Nico’s party. Notice the fact that even whilst glammed up, Sienna still manages to wear her trademark peter pan collar. This was from ASOS, originally £50 then reduced to a bargainous £16.
Sienna’s Black & White Shirt Dress

If something crazy is going on in Hollyoaks, you can pretty much guarantee the Blakes are involved in it somehow! Sienna wore the above monochrome shirt dress whilst trying to evade the police again.
Featuring a gathered waist and pockets, this dress was originally from Topshop.
Sienna’s Green Skater Dress

Back in 2014, Sienna wore a green dress with a skinny belt from New Look. We have @KellyAnnTweets to thank for letting us know that it was reduced to £8. Unsurprisingly, it sold out quickly after we featured it.
Sienna’s Blue Dress With White Collar

Skater style with a delicate embroidered cutwork collar and pintuck detail, this dress was originally £38 from ASOS.
Sienna’s Blue Floral Dress

Sienna’s striking blue skater dress with oriental botanic print and lace neckline was originally £45 from Oasis.
Sienna’s Cream Floral Print Dress

Sienna wore this lovely floral tattoo print Topshop dress numerous times from 2014 through to 2015.
Sienna’s Light Blue Layered Dress

Despite the morbid goings-on surrounding Maxine and Patrick’s renewal of wedding vows, Sienna and Nico both looked lovely in matching pale blue dresses.
Featuring a layered design and embellished collar, this dress was from ASOS and sold out after we first featured it in January 2016.
Sienna’s Mint Green Dress

This summery dress in mint green was a brief departure from Sienna’s trademark floral prints. Featuring cut-out detail at the collar, this ‘Cutwork Neck Dip Hem Dress’ was from Madam Rage.
