Loungewear that neither swims nor pinches
Short answer: Choose a soft cut with structure, meaning room in the leg but a waistband and hem that stay put. Shapeless clothing quickly becomes clothing you will not answer the door in.
The line between cosy and scruffy
The difference lies in three things: a waistband that holds, a length that was deliberately chosen and a fabric that drapes rather than bulks. All three exist in styles that are still soft to sit in.
The trousers
Choose a soft, wide waistband with a cord and a leg length that ends where you want it, not ten centimetres below. A slight taper makes the trousers look better without making them tight. See loungewear for women.
The top
A top with a defined shoulder and a hem that lies flat looks composed even in a soft fabric. A large, shapeless jumper does the opposite. See loungewear for men.
When you can go out in it
A set in a plain dark fabric with clean edges works for a walk or a parcel at the door. See sweat clothing and bamboo jogging sets for women.
Frequently asked questions
Should loungewear be a size larger
No. Softness comes from the fabric, not from extra fabric.
Can nightwear be used as loungewear
For an hour on the sofa yes. The cut is rarely made to be seen in, though.
What makes a set more versatile
Plain dark fabric, clean edges and a top that matches the trousers in tone.
