JBS of Denmark big shirt in bamboo and what it is for
Short answer: A big shirt is a long, loose top worn as a nightdress or a lounge top. JBS of Denmark makes the style in bamboo viscose, where the long shape and the soft drape are the whole point.
What a big shirt is
A big shirt is an oversized t-shirt that falls below the hips and often to mid-thigh. It is worn either as a nightdress or as loungewear with leggings. See the current styles at JBS of Denmark, where length and colours are listed in the product text.
Why bamboo viscose suits the style
Because the shirt is large and hangs freely, the drape of the fabric is very noticeable. Bamboo viscose hangs heavier than cotton jersey and creases less when you sleep in it. It is the same quality that makes the material popular for bamboo nightwear for women.
As a nightdress
Many people prefer a big shirt to a traditional nightdress, because it is loose all over and has no seams pressing at the waist. It moves with you when you turn over and does not wrap around your legs the way a narrow dress can. The length decides how much it covers.
As loungewear
With leggings or soft shorts, the big shirt becomes a calm home outfit for weekends and evenings on the sofa. It is long enough to cover the hips and loose enough not to get in the way. Choose a darker colour if you will wear it a lot during the day.
Sizing a style that is meant to be big
A big shirt is cut large, so you should normally take your usual size rather than sizing up. If you go up, the armholes become deep and the neck too open. If you are unsure, measure a top you like and compare using the size guide.
Length and height
The same big shirt fits differently depending on how tall you are. On a shorter person it can reach the knee, while on a taller person it ends above mid-thigh. Check the length measurement in the product text and hold a tape measure against yourself.
Sleeves and neckline
Most big shirts have short sleeves that fall slightly over the upper arm. That gives air and makes them comfortable at night. A round, slightly wide neckline is most common. If you sleep cold, a big shirt can be paired with a cardigan or long trousers.
Colours
Light colours feel fresh and airy in summer, while dark colours hide small marks better if the shirt is also worn during the day. Black and navy are the most practical, while grey and pale shades feel calmer as nightwear. Choose by when you will wear it most.
Washing and durability
Large tops wear most at the neckline when they are pulled over the head. Wash at 40 degrees inside out and avoid the tumble dryer, which can shrink the fabric. Lay the shirt flat or hang it over a line. See the washing guide for bamboo clothing.
How many you need
If you wear the big shirt as a nightdress, it is nice to have two or three so there is always a clean one while another is in the wash. Nightwear is washed often, and rotating several makes them last longer. Different colours let you switch with the seasons.
Frequently asked questions
Should you size up in a big shirt?
No, usually not. The style is already cut large, so your usual size gives the loose shape. Sizing up makes the armholes and neckline too open.
Can a big shirt be worn as a nightdress?
Yes, that is one of the most common ways to wear it. It is loose all over, has no seams at the waist and moves with you when you turn over in bed.
How do you wash a bamboo big shirt?
Wash at 40 degrees inside out and skip the tumble dryer. Do not pull the shirt hard over your head, so the neckline keeps its shape for longer.
