Frequently Asked Questions (FAQs) – Boys Suits & Kids Formalwear

 

What sizes are available in your boys suits?
We offer boys suits for toddlers, children, and teenagers. Our sizing chart helps you choose the perfect fit based on your child’s height, chest, and waist measurements.

Do you ship children’s suits across the UK?
Yes, we provide fast UK-wide delivery on all children’s formalwear, including page boy suits, tuxedos, and casual kids suits, with easy returns within 30 days of receipt.

What events are your boys formal suits suitable for?
Our boys suits are perfect for weddings, graduations, proms, school ceremonies, religious celebrations like first communions and bar mitzvahs, Eids, and formal family gatherings.

How do I choose the right suit for my child?
Consider the occasion, your child’s comfort, and the season. For formal weddings, we recommend tailored or tuxedo suits. For summer events, linen, slim-fit styles, or a waistcoat suit set offer breathability and style.

What is the best suit style for a summer wedding?

Lightweight fabrics like linen or cotton, especially in lighter shades (beige, cream, pastel), are recommended for keeping boys cool and stylish during summer ceremonies.

What should a page boy wear to a wedding?

Most page boys wear a formal suit, often matching or coordinating with the groom or groomsmen. Popular options include waistcoat suits, tuxedos, or tailored three-piece suits. Page Boy suits also tend to come with 4-piece, 5-piece, and 6-piece options, including the matching accessories that come with the suit.

Do page boys wear accessories like ties or buttonholes?

Yes, bow ties, ties, waistcoats, and buttonholes are frequently used to elevate a page boy’s outfit and align with wedding party styling, that is why we offer page boy suits with 4-piece, 5-piece, and 6-piece options, which include the matching accessories that come with the suit.

What age is appropriate for boys to wear suits?

Boys as young as 1–2 years old can wear suits for weddings, christenings, and formal events. SIRRI offers sizes from toddlers to teens.

Can boys wear suits to a school graduation or prom?

Yes! Boys suits are a popular choice for school events like graduation or prom. Slim-fit tuxedos  are especially on trend for teens.

Should a boys wedding suit match the groomsmen?

It’s common but not required. Matching the page boy suit to the groom or groomsmen looks great in photos, but complementary styles also work well.

How do I measure my child for a suit?

Use a measuring tape to measure chest, waist, and height. Refer to our sizing guide to choose the closest match for a comfortable fit.

Are there black tie suits for boys?
Yes! We offer boys tuxedos and black tie suits perfect for formal evening events.

What accessories go with a boys suit?
Popular accessories include bow ties, pocket squares, waistcoats, suspenders, and formal shoes. These can be colour-matched to the event theme.

Do you offer matching suits for siblings or father and son?

While full matching sets may not be standard, we do offer suits in coordinated colours and styles for sibling or father-son outfits.

Can boys suits be altered or tailored?

Our suits come in various fits, including slim and tailored. We do not offer an alteration service, but a few designs come with unfinished hem trousers that the buyer can later tailor for a perfect fit.
