Why Choose Us for your Prom Dress Alterations?

At Alterations Boutique we are committed to excellence. Our highly experienced, fully qualified seamstresses will work as long as it is required to create the perfect fit for your prom dress, and we won’t be completely happy with the results until you are. Altering Your Prom Dress: What Can You Change? We have established an excellent reputation for delivering impeccable quality alterations when it comes to restyling, resizing, remodelling, altering or repairing Prom Dresses. What sets us apart is our ability to work to a factory finish which means that any Prom Dress alterations we perform will be unnoticeable and untraceable; the original stitch pattern, thread colour and any detail will be matched perfectly. This makes us the number one choice for any Prom Dress alterations in London. We are highly regarded because of the quality of work we perform, award-winning customer service we provide and reasonable prices we charge. 


Alterations Boutique Limited is a VAT registered company with a comprehensive insurance policy that covers your Prom Dress whilst it is in our possession. Unfortunately, there are individuals that have set up rogue businesses that do not pay tax, take cash only and do not have the correct insurance in place which means you and your garment have no protection. We are proud to be a British company that complies with all rules and regulations to provide peace of mind to our clients.

The Team 

All of our team are qualified Dressmakers or Tailors by trade. Despite being already qualified, the team have to undergo a rigorous Alterations Boutique training programme to demonstrate they perform work to our high standards. In addition, there is ongoing regular training to help the team master their skills.

Prom Dress Alterations Costs

We believe in charging our customers fair and reasonable prices, therefore, we undertake regular research to ensure our rates are moderate. We appreciate that you would like to know in advance how much the costs are going to be but as Prom Dresses can vary with regards to fabric, finishing, construction and detail we prefer that customers visit us so we can provide a free, accurate and no obligation quote. At your appointment, we will provide you with a breakdown of costs so you have a clear understanding of what you are being charged for and do our best to make sure we quote within your budget. Our Fair and Reasonable Price policy means that our customers receive the best possible service and outstanding quality workmanship, without having to pay premium prices.

All fittings including the consultation are free. We only charge for the work we perform and you only pay for the work we agree to do once. For example, if we take in the dress and it still does not fit correctly when you try the dress on, we do not charge again.
