Kostüm Kaiser

Kostüm Kaiser has been renting out costumes near Basel since 1882, and its own homepage still opens with exactly that line: "Verkleiden ist seit 1882 unsere Leidenschaft" (dressing up has been our passion since 1882). The shop calls its own stock, more than 40,000 pieces spanning, in its own words, "von der Steinzeit bis hin zur Mode der heutigen Zeit" (from the Stone Age to today's fashion), the largest costume collection in Switzerland, and almost none of it has anything to do with weddings: gladiators, monks, Beatles suits, Appenzeller folk dress, company mascots. Formal wedding wear sits inside that catalogue as one clearly bounded department, Herren-Abendbekleidung (men's evening wear), not as a separate bridal-menswear business with its own shopfront or its own brand.

What that department does well is sort its 3 main pieces by exactly what kind of wedding they're for, in both its German original and its own maintained English pages. The tuxedo (Smoking) is pitched broadly: "Ideal for weddings, opera visits, concerts, and formal evening events," worn whenever an invitation calls for black tie. The morning coat (Cut) is aimed specifically at daytime weddings, worn only before 6pm, and the German original goes further, naming it directly as "Outfit für den Bräutigam", the groom's own outfit, rather than just formal daywear in general. The tailcoat (Frack) sits at the top of the scale, reserved in the site's own words for "the most formal dress code for evening events such as prestigious balls, gala dinners, and large weddings", worn only after 6pm and specifically when a wedding calls for white tie. All 3 come from Wilvorst, a named formalwear brand the shop calls its "exclusive" evening-wear collection.

Wilvorst off the shelf, not cut in the shop's own workshop

Kostüm Kaiser hires garments out; it does not cut a suit to your own measurements. The company does run its own tailoring workshop, Kostümschneiderei, that builds pieces to individual measure, but that side of the business makes historical costumes, uniforms, company mascots and guild ceremonial dress, not the Wilvorst wedding line. The tuxedo, morning coat and tailcoat all come in stock sizes 44 to 60, plus long fits (90 to 114) and short fits (24 to 31); slimline cuts exist only for the tuxedo, and only in sizes 46 to 52. Nothing on the site mentions alterations to these particular rental pieces, so getting a good fit means picking the right stock size rather than having one taken in afterward.

The usual way to settle that size is a try-on visit at the Aesch shop; no appointment is required, though the site says booking ahead is welcome. That visit can happen as much as 3 months before the event, or as late as 1 to 3 days out, close enough that you walk away with the suit the same visit. If you cannot come in person, Kostüm Kaiser will work from measurements instead, sent online, by email or by post, and its own measurement sheet spells out exactly what a man needs to provide: height, head circumference, collar size, chest, waist, sleeve length, inseam and, if you want the shoes too, shoe size, ideally taken by a second person rather than guessed alone. The rental page also runs as a genuine English translation, not a machine rendering, at its own English-language URL, which is at least a sign that English-speaking customers are routine business here, even though nothing on the site states outright that a phone consultation itself runs in English.

CHF 230 to CHF 359, printed down to the cufflinks

Prices are unusually plainly printed for this category, and every one of them includes Switzerland's 8.1% VAT. A tuxedo (jacket, trousers, bow tie, cummerbund) runs CHF 230; a morning coat (jacket, waistcoat, striped trousers, cravat, pocket square) CHF 260; a tailcoat (top hat, jacket, waistcoat, trousers, white bow tie) CHF 260, or CHF 340 for the white version worn only at the most formal daytime events. A plain black or dark suit is CHF 166. Add-ons are priced separately and consistently across all 3: a wing-collar shirt is CHF 39, cufflinks CHF 11, patent leather shoes CHF 39, a standalone waistcoat CHF 66, a standalone cummerbund CHF 22. Worked through, the shop's own typical-total figures land a tuxedo at CHF 230 to CHF 319, a morning coat at CHF 260 to CHF 349, and a tailcoat at CHF 260 to CHF 359, depending on what you add to the base piece.

Those are one-event prices. Wear the same rented outfit for a second occasion, a rehearsal dinner as well as the ceremony, say, and the shop charges 150% of the base rate rather than a full second rental; a third occasion is 175%. Paying in person is cash or debit card only; Kostüm Kaiser states plainly that it does not accept credit cards. An order shipped rather than collected arrives instead with an invoice and a Swiss payment slip. If a costume is delivered and then not used, the full price is charged; a late cancellation, illness or force majeure is billed at half that.

What doesn't reach a mailbox abroad

The site describes delivery as generally possible "within Switzerland" (very large or long items and firearm replicas aside), sent by priority post, with the return required by signed post at minimum and due back within 2 working days of last use. Nothing on the site claims international shipping, so a couple based abroad should plan on a fitting visit in Aesch, a Swiss delivery address such as the hotel or venue, or someone local who can collect and forward the parcel; renting sight unseen from another country isn't something the site offers as a service. Cleaning is included in the rental price unless a costume comes back heavily soiled or damaged, which is billed separately.

Aesch, not Basel, and only on a weekday

Kostüm Kaiser sits in Aesch, a municipality roughly 15km south of Basel in canton Basel-Landschaft, not in Basel itself: reachable by car via the H18, by tram (line 11 to its Aesch terminus, then a short walk), or by train on the S3 to Aesch station, with a connecting bus that runs twice an hour. The shop keeps conventional weekday hours, Monday to Friday, 07:15 to 11:45 and 12:45 to 17:00, closed on weekends and over the midday break, with no indication anywhere of Saturday viewings or evening appointments. A couple flying in for a weekend wedding should plan the fitting trip around a weekday, not assume the shop is open when they land.

The honest read

Set against a category mostly built around bespoke and made-to-measure tailors who publish little beyond an offer of a consultation, Kostüm Kaiser is the plain opposite case: a costume-rental house running since 1882 that prints its full price list, its size range and its cancellation terms in public, and that will build an order from a mailed-in measurement sheet if a couple cannot get to Aesch in person. It will not produce a suit cut to a groom's own shape, and it will not post a tuxedo abroad. What it will do is put a well-priced, named-brand formal outfit into a groom's hands on a few days' notice if that is all the time there is, matched to the wedding's own dress code: a morning coat for a daytime ceremony, a tuxedo or a tailcoat for an evening one.
