Men's dress shirts for small DFAB individual

I live in the uk so you might not find the brands I suggest but it's worth a look. I was the absolute smallest size in woman's clothing so finding men's has been a struggle for me too. Dress shirts are measured around the neck in inches and then by fit e.g. Regular, slim, skinny. The way to measure your neck size is to wrap a tape measure around it and make sure you can still fit two fingers down the front. I'm about a 13.5/14 but I actually managed to find a 12.5 recently and it's a little tight but does the job. As for fit, unfortunately if you're extremely petite as I am, only the skinny fit shirts are going to be worth looking at. I'm not sure if you'll find any that do long/regular/short lengths, I haven't, but it's worth a look.

H&M for me has always run too big in any of their dressy clothes but trying them on is the only way you'll know if they fit you. My go to shops are Next, River Island (goes down to 12.5 inches) and Top Man.

Edit: Just read that you don't have a tape measure. Get a piece of string or even a pair of earphones will do, wrap it loosely around your neck and hen use a ruler or any other available measuring tape you have to measure the length of th string.

 

Maybe try looking in the boys section. If you do find something in a boys size, once you buy it and wear it, no one will know.

 

Speaking from personal experience you should probably just go to the store and try them on. There are countless ways in which male dress shirts refuse to fit to the female body the way you want them to and it varies from piece to piece.

H&M is not bad but it's not really quality work either it's cheap so that's a plus but the designs aren't that good and the fabric is very thin so not good if you are looking for something substantial. A few pieces are fine though so again looking is your best bet.

 

I dunno if Uniqlo's Japanese sizing is different but I wear a Small or Medium dress shirt from them and I used to buy Sm in the women's section (depends on if I'm binding and the cut, what size I get). I also shop at H&M, usually Medium from them (I find they fit smaller).
