We should take good care of the things we love. Here are Boom Butik's best tips for giving your clothes a little love:
- Wash your clothes a little less often. Many splashes and stains can be fixed by hand.
- Kiss your tumble dryer goodbye. It is really handy, but it is your clothes' worst enemy. Air-drying all the way!
- Tell your clothes that you love them. There are very few things in this world that do not benefit from a little love.
- As far as possible, avoid washing above 30 degrees.
- Use a detergent that does not contain too many toxic substances and that is gentle on the environment. Your clothes and your skin will thank you.
- Appreciate your clothes and give them some love. You can never give too much of that.
Love, Boom

Our friends at the warehouse really, really try to minimise the number of mistakes in the parcels, but unfortunately it can happen sometimes 😌 If there's been a packing error in your order, please write to us at hi@boombutik.com. Then our super-sharp and lovely customer service team will take care of it! Unfortunately we can't be reached by phone, but we'll make sure to fix your problem as quickly as possible - and for these mistakes we of course always cover the extra shipping costs 🤝
Every now and then it unfortunately happens that we send out an item with, for example, a seam that has come undone. We try to look the clothing over carefully, so luckily it doesn't happen very often, but if you experience it, please write to us at hi@boombutik.com or on insta. Then Louise, Felix or one of the others will get the problem sorted as quickly as possible ⚡

When the gift card is purchased, you'll receive an email with a code 🤗 Enter this code to the right of your contact details, in the field labelled "enter discount code or gift card".
Did something go wrong when you ordered, or do you regret something you've ordered? Send an email to "hi@boombutik.com". Feel free to write "URGENT" in the subject line, so we can really tell it's urgent! Then we'll do our best to cancel or change your order before it's packed!
This is most often because there's a mistake in the email address, or because it has ended up in your spam filter. If you can't find the email in your spam filter, please write us an email with the phone number and/or name you used to place the order. Then we'll resend the order confirmation to you!
The best thing you can do in this deeply, deeply unfortunate situation is to sign up for the item you want with your email address here on the website. As soon as the clothing is back on the shelves, you'll receive an email with a link straight to ordering ⚡
You're of course also always welcome to write to us at hi@boombutik.com or insta, and we'll give you our best guess as to when the item will be back.
Yes, we have a little store at Blågårdsgade 14, 2200 Copenhagen N, open every day of the week from 12 PM to 6 PM. In addition to our regular range from the website, we also sell seconds there at an even better price.
We'd actually say the clothing fits pretty true to size. So we generally recommend going with the size you usually wear. But we ourselves wear lots of different sizes depending on how we want it to fit. For example, I - the guy sitting here writing this FAQ - own clothing from this shop in everything from M to XXL.
Our clothing is as basic as it gets, so it isn't intended for any particular gender or body type - we really think everyone can wear it.
As a rule of thumb, go with the same size you're used to 🤗 If you're in doubt, you can also use our size guide, which you'll find below the product description.
