Consistent quality, returning customer

This is my third purchase from Castleson DK, and they continue to deliver. This time I got a 'business jakkesæt' and a 'strygefrie skjorter'. The fit and material quality are consistently good, just like my previous 'bryllupsjakkesæt' order. Their sizing guides are accurate, which saves a lot of hassle. I appreciate the reliability; it's why I keep coming back when I need formal wear. Delivery was also on time, no issues.

Amazing 1920s suit!

I absolutely loved the '1920er jakkesæt' I bought! The material felt fantastic and the fit was perfect right out of the box. I also picked up some 'manchetknapper' and a 'slips' that completed the look. I'm so happy with how everything turned out. I will definitely be shopping here again for future events, and I've already told my brother he needs to check them out!

Nice tweed suit

Bought a tweed jakkesæt. It arrived quickly and looked just like the pictures. Happy with the purchase.

Good suit, slow delivery

I ordered a '3-delt jakkesæt' for an event. The quality is quite good for the price, and it fit well after a minor alteration on the trousers. What could be improved is the delivery; it took 7 days to arrive, which felt a bit long. Customer service was responsive when I inquired about the shipping status, which was a plus. Overall, a decent value, but plan for shipping times.

How's the quality on these suits? Are they actually good for the price or more like fast fashion stuff?

G Grace Carter 1 week ago
Way better than fast fashion. My wool suit feels really solid, holds up great.

K Karen R. 1 week ago
Honestly, for the price, the quality is really good. Definitely a step up from like, Macy's or something. I've had my tweed one for a year and it still looks new.

Hey, I'm looking at getting a suit for a wedding next month. How long does shipping usually take to, say, Seattle?

R Ryan Roberts 1 month ago
Mine got to California in about 10 days, give or take. So a month should be plenty of time, I think.

They ship from Denmark, so yeah, it's not super fast. But I got my tweed jacket in under two weeks to NYC. Might depend on what you order too.

Thinking of getting one of the 3-piece suits for my graduation. Does that automatically get a discount, or do I need a code?

J Jason N. 2 weeks ago
Yeah, I think the bundle discount for the 3-piece sets just applies automatically in your cart. No code needed.

Can confirm, got a full suit set last year and the discount showed up right away at checkout. Super easy.

I signed up for their newsletter, does the welcome discount apply to everything, even sale items?

A Amanda Phillips 1 month ago
Usually newsletter discounts are for full-price items only, afaik. Sale items are already discounted.

B Brittany Roberts 1 month ago
My experience with other stores is that welcome codes usually don't stack or work on already reduced stuff. But you can always try it at checkout and see!

Do Castleson suits run true to size or should I size up/down? Kinda worried about ordering online without trying it on.

Z Zach Campbell 1 month ago
I found them pretty accurate. Just follow their size chart, it was spot on for me.

My blazer was a little snug, but my pants fit fine. If you're between sizes, maybe go up for the jacket part, especially if you want a bit more room.

Is there free returns if the suit doesn't fit right? Don't want to get stuck paying for shipping back to Denmark.

M Mary Rivera 3 weeks ago
They do offer free returns, you just gotta follow the process on their site.

A Alex Gomez 3 weeks ago
Yep, free returns are a thing. I sent back a waistcoat that didn't fit and it was no hassle at all. They provide a label.

Are Castleson suits worth it compared to Suitopia? Looking at a custom fit vs a standard size.

T Tim P. 1 month ago
Depends if you NEED custom. Castleson is great for off-the-rack and their sizes are pretty good, but Suitopia is all about that made-to-measure.

M Melissa Jackson 1 month ago
I looked at both. If you're a standard size, Castleson is probably better value. If you're hard to fit, Suitopia might be worth the extra cost for the perfect fit.

They have a bunch of payment methods, including PayPal and regular cards. Pretty standard stuff.
