I'm job hunting after being at home/out of the workplace for over 15 years. Currently live in jeans and trainers and don't own much else so I'm going to need firstly an interview outfit and then an entire work wardrobe 😱 Hate shopping and have zero interest in my appearance so can only cope with thinking about the interview outfit for now and was looking for some tips on what might be suitable these days?
Jobs I'm going for are entry level, basic admin/customer service type roles so probably customer facing but I will also need to be comfortable, I'm fat, menopausal and autistic so there will be some sensory/comfort considerations. I'm only 5' so short and dumpy probably sums me up although there is still a vague hourglass shape going on, big boobs and hips. I have dark hair and very pale skin if anyone needs to know for colours.
I have black trousers that fit but need everything else including shoes, ideally ones that feel like trainers to wear! Budget is cheap, like Primark/Matalan cheap please 
Any help/pointers would be massively appreciated, I'm genuinely clueless.
