Receiving an invitation to a Black tie event often brings a mix of excitement and uncertainty. You want to look impeccable, but the dress code feels strict and slightly intimidating. To make the process easier, we've made this guide which combines the traditions Black Tie and how that translates to the convenience hiring with ACS Rental. It should answer any questions you may have about what each Black Tie dress code really means and how to achieve the perfect fit without the cost of buying formalwear.
What is Black Tie?
Black tie is traditionally an evening dress code worn after 6pm and is reserved for occasions such as awards ceremonies, dinners, milestone birthdays and weddings. It sits below White tie in formality but remains smart, structured and deliberately refined. When executed correctly, it creates a clean, timeless silhouette that works across a wide variety of events.
Traditional Black Tie
At its core, Traditional Black tie requires a dinner suit, often referred to as a tuxedo. Savile Row tailoring describes this as a black wool suit with satin peak lapels and a matching satin stripe running along the outseam of the trousers. This design remains the benchmark of formal eveningwear.

ACS Rental offers classic dinner suit hire packages that follow this standard closely. Jackets maintain clean lines, structured shoulders and a sharp evening silhouette. For customers wanting a modern twist, velvet jackets in dark tones are also available and work particularly well in midnight blue, which often appears darker than black under artificial light.
The Dress Shirt
Black tie shirts should be white dress shirts with a Marcella bib front, French cuffs and a structured collar. Everyday business shirts can technically be worn, but they lower the overall formality.


ACS Rental provides dress shirts that follow this guidance, ensuring they hold their shape, support a bow tie and complete the clean line expected of eveningwear. French cuffs also allow customers to add cufflinks, which enhances the final look.
The Bow Tie
Black tie requires a black silk bow tie. It should be proportional to your collar and face shape. Other colours may be acceptable at creative events, but traditional Black tie remains firmly loyal to black silk.

We offer customers with pre tied bow ties, which works for those not experiences with bow ties (it is an art form!). This ensures the bow tie remains proportional, polished and comfortable throughout the event.
Footwear for Black Tie
Shoes should be formal and well polished. Patent Derbies remain the traditional choice, while velvet slippers offer a refined alternative for guests seeking something more distinctive. Office shoes or casual styles should always be avoided.
Customers who purchase our Complete Hire Packages, will receive a pair of polished formal shoes, which have the benefit of pairing perfectly with the outfit that match the expected level of formality.
Optional Accessories
Accessories for Black tie should be subtle and carefully chosen. We suggests a classic dress watch, understated cufflinks, dress studs for shirts that require them and a folded white pocket square. A cummerbund is not mandatory but helps to create a sleeker line by covering the shirt fabric that sits below the jacket button.
ACS Rental includes these finishing touches as optional add ons, allowing customers to complete their outfit with confidence and avoid unnecessary guesswork.
Modern Variations of the Dress Code
Black tie has evolved to encompass several variations. Understanding these helps guests select the right level of formality.
Black Tie Optional
Guests may choose either a tuxedo or a dark, well tailored suit. We offer suits that fit both choices and ensures whichever route is taken looks deliberate and correctly fitted.
Creative Black Tie
Events with this dress code allow for texture, colour or personality within a formal structure. Velvet jackets, subtle patterns and richer fabrics are acceptable when balanced correctly. We provide alternative styles that work well in these settings while maintaining the quality expected of formal eveningwear.
Black Tie Preferred
This encourages tuxedos but allows flexibility. A smart dark suit is acceptable if the event leans more contemporary. Customers have access to both options so they can match the tone of the event confidently.
Highlandwear as a Black Tie Alternative
In Scotland and at culturally significant events, Highlandwear stands as an equal to Black tie. The Prince Charlie jacket is considered evening formalwear and mirrors the role of a tuxedo. Its cropped structure, polished detailing and matching waistcoat create a sharp silhouette when paired with a kilt in a traditional tartan.


ACS Rental offers Prince Charlie and kilt packages that meet full Black tie standards. These are especially popular for weddings, gala dinners and celebrations with Scottish heritage.
Ensuring the Perfect Fit with ACS Rental
Regardless of the version of Black tie you follow, the outfit only works when it fits well. We want to reinforce the importance of correct proportion, clean shoulder lines, balanced lapels and structured shirt fronts. ACS Rental brings this standard into the rental market through:
- Clear measurement and fitting guidance
- Early delivery windows to allow for try ons
- Free replacement sizes if needed
- Garments that are professionally cleaned and quality checked
This process ensures each customer receives a polished and comfortable fit without the cost of buying a tailored suit.
What Not to Wear
For any explicitly formal dress code, avoid casual clothing entirely. This includes trainers, jeans, T shirts, jumpers, patterned shirts and overly bright or novelty accessories. Avoid suits that are not black or midnight blue, and never wear a white bow tie, as this belongs strictly to White tie events.
Bringing the Look Together
A Black Tie dress code is designed to elevate an event. It looks impressive, photographs well and creates a sense of occasion. With ACS Rental, customers gain access to high quality formalwear, knowledgeable guidance and a reliable fit, whether they choose a traditional tuxedo, a modern Slim Fit suit or a Prince Charlie Highlandwear ensemble. We're here to simplify the process and ensures every guest arrives feeling prepared, confident and appropriate for the evening ahead.
