The neckline has gone slack

Short answer: A slack neck comes from the neck rib being stretched, most often when the top is pulled over the head with the hands in the edge. Moisture and flat drying tighten it again, but only for a while. Grab the shoulders instead of the neck edge.

The neck takes the most stretch

The neck edge is the narrowest part of the top, so it takes the most stretch when you pull it on. The head has to pass through the opening, and the rib has to give way every time. That is why the neck is often the first place to lose its shape, before the rest of the top shows any wear.

The rib stretches a little every time

Each time the top is pulled on, the rib grows a little longer and does not spring fully back. You see it after a few months, even on items with a narrow edge such as bamboo panties. It happens gradually, so you rarely notice until the neck suddenly hangs loose.

Hands in the edge are the problem

The worst habit is grabbing the neck edge itself when you take the top off or put it on. The hands pull the rib sideways, and it stays that way. Grab the shoulders instead, or the fabric a little further down. It is a small change, but it spares the edge every time and costs nothing.

Heat makes it permanent

If the rib is stretched while the fabric is still warm from the tumble dryer, the new shape is locked in. That is why a slack neck is often worse on clothes that are regularly dried warm. It affects bamboo sweat clothes in particular. Air dry them so the rib is not fixed in a stretched form.

How to tighten it up

Dip the neck edge in warm water, press it together and let it dry flat without stretching. The moisture and flat drying help the rib draw back together. Lay the top on a clean surface and smooth the edge with your fingers so it lies as it should. Do not touch it until it is completely dry.

Does it work on every top

The method works on most of the most popular styles from Copenhagen Bamboo. If a top has a very wide or heavily stretched neck, the effect is smaller. You can always try, as it costs only some warm water and patience. Go carefully and do not pull on the edge while it is wet.

Does the tightening last

Not forever. The tightening lasts a couple of months at a time and has to be repeated after a number of washes. See it as part of the care, like washing and hanging up. If the edge keeps giving way, the rib is worn enough that it can only be helped a little.

Can the neck be sewn in

Yes, a tailor can take in the edge, but it changes the shape of the neck. The neckline becomes narrower, and the top gets a different look at the opening. It is a solution for tops you want to keep and can live with in the new shape. Ask the tailor how they would approach it first.
