Garment Care for Tees & Hoodies

Garment Care: 
 To keep your cotton T-shirts & hoodies looking as good as new, follow these easy care tips:
Wash with Care – Cold wash on a gentle cycle to keep the fabric soft and the print looking sharp.

Turn Inside Out – This helps protect the design from wear and tear in the wash.

No Harsh Stuff – Avoid bleach, fabric softeners, or anything that sounds too aggressive.

Keep it Cool – Air dry for best results, or tumble dry on low if you must (but we love a good old-fashioned clothesline!).

Ironing? Ain’t Nobody Got Time for That! – But if you must, iron inside out and avoid direct contact with the design.
 Follow these tips and your favourite cheeky tees & hoodies will stay looking fresh, wash after wash! 

Care Instructions for Tumblers, Glasses & Mugs

To make sure your sassy sipware stays in top-notch condition, follow these simple care tips:


Hand Wash for Best Results – While some items may be dishwasher-safe, we recommend hand washing to keep the designs looking crisp and vibrant.

Avoid Extreme Heat – No microwaving for tumblers or insulated cups. 

Gentle Cleaning Only – Use a soft sponge (no harsh scrubbing or steel wool – your cup deserves better!).

Let It Air Dry – Keeps everything fresh and prevents water spots.
 Follow these tips and your mugs, tumblers & glasses will keep bringing the sass, sip after sip!

Why made to order matters

At Simpli Must Have, every piece is made to order — on purpose. 

 

We don’t mass produce or pump out piles of stock that might never be loved.

Instead, we create each item just for you, once you click “Add to Cart.” 


It means a whole lot less waste. 


By printing to order, we reduce overproduction, keep things sustainable, and make sure what you get is made with intention (and a dash of cheek, of course). 

It’s better for the planet, and way better for your wardrobe

Sustainable Products & Shipping matter to us

The materials we use are carefully considered and come straight from responsible factories with ethical accreditations.

 

We also use shipping partners that have 100% Carbon Neutral Delivery.

FOUNDER STORY

Family Fuelled

Founded by a chaos-loving mum who loves a family dress up and wearing tee's that say something fun, Simpli Must Have was born in our home office — fuelled by coffee, funny occassions, and kid-powered creativity. 

 

What started as a side hustle between school runs and snack demands quickly turned into a full-blown brand, with our 4 little humans pitching in on ideas and helping make the gear (and testing, of course). 

 

Every design has a story, a giggle, or a “Muuuum (or Bruh), you should put this on a shirt!” moment behind it — because around here, family-made means heart-made.
