These days you'll find us slumped at a laptop still in our pyjamas, or leggings and slippers if we're dressing up. Almost all pretense of normalcy is gone and with it maybe our posture, so that's why Celia Holman Lee's tips on "carriage" is just the content we need – even if some days it's purely aspirational! 

As one of Ireland's best-known models and owner of the Celia Holman Lee modelling agency, Celia has built a reputation as one of the country's most glamorous women, and has been helping us all stand a little taller these days with her video tutorials on Instagram and Twitter. 

Donning a stunning gúna and freshly blow-dried hair, Celia is the just the glamor puss we need to add some dazzle to our days. 

"I'm asked a lot, have you any secrets, what do you do? I feel posture is your God-given gift and it's free", she says in one video. 

It turns out the secret to good posture isn't setting your computer screen a little higher, but all in the shoulders, bum and tum. 

"Bring your ears over the shoulders, and your shoulders back and down", she says. "Straight away you've the greatest gift, which for me are your shoulders." 

"Tuck your bottom in and that will automatically bring the muscles of your tummy in. You're automatically exercising slightly, just tightening the muscles."

Look good in your dressing gown and accidental working out? Sound.

If you want to really impress your cat first thing in the morning, you can make an entrance by perfecting your walk. Carriage is everything, Celia says, and from the looks of it, walking tall could turn a duvet into an ensemble

Start with perfect posture, with ears over the shoulders and shoulders down. When walking, she says, don't jut out your bum and your neck. Instead, take long steps. 

Finally, now is the perfect time to master selfies but what about those group shots once festivals, gigs and pubs start back up? If you want to stand out, there's a pose for that. 

Starting with perfect posture, the difference is in the legs, Celia says, "to give that fabulous silhouette".

"Lift your leg to get into the position and bring it in. Lift up the knee, then you can bring the toe out to the right." To help stop you looking "boxy", she says, bring the shoulder on the same side as the lifted kneed over slightly.

"Never put your hands on your hip area. Always on your waist." To make sure you're looking straight into the camera, "put your chin on the mantlepiece", she jokes. "And smile!"
