A mini portfolio or comp card gives the photographer a preview of how you are with the camera, what are your comfortable and favourable angles etc. It gives an insight of you as a professional. It also represents your seriousness as a professional model and leaves a great impression.
Black/white/nude inner-wears are the saviours for any shoot where you have no idea of the garments you are going to wear. You will have the necessary undergarments to match with costumes not only to make you comfortable at the shoot but it also makes things easier for your stylist and the photography team.
No matter there are inventories at the studio or not, it’s always safe to carry some footwears to your shoot. A pair of sport-shoes or heels that you’re comfortable in, will relieve you of the stress of matching garments with footwear for full length shots.
Own a ‘modelling kit’ and take it on all shoots. These are the things you will need but may not be directly mentioned in pre-shoot communications. They are outdoor/studio shoes, nude/black underwear, face wipes, moisturiser/oil for your legs, a plain vest top, safety pins/clamps, your own water with a sugary snack to keep you going, spare stockings for lingerie shoots.
Carry Confidence. A huge part of modelling is simply feeling great in your own skin. It takes time, but it will make you a happy and successful professional.
