Hooks and eyes or snap fasteners – the choice depends on the direction of the load. A hook and eye holds best under sideways tension, for example above an invisible zip or on a waistband. Snap fasteners close with pressure and are convenient where the garment is opened often and quickly, but they come undone under strong pulling. Trouser hooks and bars are for heavily loaded waistbands, and hook and loop for adjustment and children’s clothing.
The five concealed closures at a glance
- Hooks and eyes (wire hooks and eyes) – bent from wire, sewn on by hand; for dresses, blouses, skirts and lingerie.
- Trouser hooks and bars – flat, stamped hooks; for trouser and skirt waistbands.
- Sew-on snap fasteners – two parts that click together, sewn on with a needle; for plackets, flaps and lingerie.
- Press-on snap buttons – attached with a press or pliers; for jersey, children’s and sportswear.
- Hook and loop (Velcro) – a tape with hooks and loops; for children’s clothing, cuffs and adjustment.

When to choose hooks and eyes
A hook is best where the two edges must be drawn together closely and stay in line under tension. It does not come undone when pressed from the front, because it works like a hook – it only opens when you lift it. That is why it is standard:
- at the top end of the invisible zip on dresses and skirts;
- on necklines and backs fastened edge to edge;
- on lingerie – as single sets or as tape;
- on fine fabrics that cannot be pierced with a press.
The drawback is that it is slower to fasten and is sewn on by hand. Browse the styles in the wire hooks and eyes category.
When to choose a trouser hook and bar
Trouser hooks and bars are wider and flatter than wire hooks and withstand constant tension. They are used mainly on waistbands of trousers and skirts in suiting or denim fabric. If a wire hook on a waistband bends or slips, a trouser hook and bar is the right replacement.
When to choose snap fasteners
Sew-on
Sew-on snap fasteners are suitable when the garment must open quickly and often and the load is small – plackets on shirts and blouses, pocket flaps, lingerie straps, children’s clothing. They hold under pressure, but come undone under strong sideways tension, so they are not used above the zip of a fitted dress.
Press-on
Press-on snap buttons are attached by machine and are stronger. They are standard on baby bodysuits, jackets, sportswear and items in jersey and denim. They are not suitable for fine silk or chiffon, because they pierce and distort the fabric.
When to choose hook and loop
Hook and loop is practical when the circumference needs to be adjustable or a child needs to dress themselves. It is stiff and noisy compared with hooks, so it is not used on formal or eveningwear. In addition, the hook side catches fine fabrics and knits in the wash, and on thin fabrics the tape shows as a dense strip.
Hook and loop makes sense on workwear, jacket cuffs, children’s clothing and adaptive clothing for people with limited mobility, where speed and ease of fastening matter more than discretion.
How to decide for a specific style
If you are undecided, ask yourself the following questions in turn. They cover most practical cases in womenswear:
- How strong is the sideways tension? High and constant – trouser hook and bar. Medium – hook and eye. Low – snap fastener.
- How often is the closure opened? If it is opened many times a day, for example a lingerie placket or a pocket flap, a snap fastener is more convenient.
- What is the fabric? Fine and sheer fabrics only tolerate sew-on closures. Jersey and denim tolerate a press.
- What is the production like? Press-on snaps are fast for large runs but require equipment. Hooks and sew-on snap fasteners are attached by hand without machines.
- Who will fasten it? Children and older people find snap fasteners and hook and loop easier than small hooks.
The answers usually lead to one clear closure or to a combination of two that covers the different areas of the style.
Combinations that work
- Invisible zip + hook and eye – the classic on dresses and skirts.
- Zip + trouser hook and bar – on trousers and skirts with a waistband.
- Hooks at the neckline + snap fasteners on the straps – on complex evening styles.
- Snap fasteners + visible buttons – on shirts with a concealed placket.
Common mistakes when choosing
- A sew-on snap fastener above the zip of a fitted dress – it opens when sitting down.
- A wire hook on a denim waistband – it bends.
- A press-on snap on chiffon – it tears the fabric.
- Hook and loop on an evening dress – it catches fine fabrics and is noisy.
