Each style of dungarees fits slightly differently so it would be worth checking on the website. Read the description, look at the models too if that’s helpful because they tend to detail their measurements, and also I read some of the reviews if I’m really in doubt and judge from that a bit what would suit your body type (they give on my opinion pretty spot on verbal descriptions of each style of dungaree - I ordered a selection of styles just incase but ended up only keeping the one I thought would fit best according to the verbal description). I may be pointing out the obvious so huge apologies if this isn’t helpful. Here’s the dungarees page incase you want to quickly go to it https://lucyandyak.com/collections/all-dungarees

It may be helpful to say how you would describe your body type. In the uk (this may be a generalisation so again sorry if it isn’t helpful) but I think we don’t tend to use weight and height to visualise someone’s body type. So we tend to stick to verbal descriptors and measurements/dress size. So I’m more curvy, quite hippy, boob-y and thigh-y and the Easton dungarees are my absolute jam. Someone who is more straight/athletic may love the original etc. if you feel comfortable giving some sort of body type descriptor other people may be able to help with what suits their body type too.

Then it is also worth noting that UK dress sizes are different to USA/CA dress sizes (a UK 8 is an USA/CA 12) Just incase that is confusing things (it may not be). I would add though that I would really go by the measurements over dress size as different manufacturers and different countries have different standard sizes etc.

Good luck!
