how often do you think you should take your measurements?
this is a REALLY good question, anon!!!
i typically keep mine on my phone in my notes for easy access and i haven’t updated mine in probably a few months–but i think the best practice would be to retake them any time you’re doing an order from a brand new place that you might not be as sure with the sizing as you are some of your mainstays.
like, i don’t even look at the size chart for forever21 or torrid any more, i’ve been the same size at both of those places for a long time and the size difference is significant enough that i would not bother retaking my measurements before making an additional order. HOWEVER. if i was buying something where very specific measurements are listed–like a one size fits all item on a chinese based website like aliexpress or something similar, or a buying a vintage piece off of etsy then i would absolutely make a second check just to make sure that i’m good. there’s a really big difference in terms of accuracy when you’re buying something that has very fixed measurements versus buying from a much more standardized chain store.
also–any time that you’re looking to make a larger order from a new place. when i made my first bigger order with boohoo i rechecked my measurements first, and that way i could familiarize myself with their size chart with fresh information and make sure that for my first bigger order i was making good choices.
i don’t think like, there’s a really good concrete time frame that you should re update things–it depends so much on your body and metabolism and if you have a lot of weight fluctuation or not–if you’ve been actively doing something to change your measurements (like trying to get BUFF) then it’s definitely a good idea to update that information so you’re not buying stuff way too small for you or w/e.
but yeah–to sum up, right before a big purchase at a new place is always a good opportunity to update this information, or any time you’re looking to purchase something with extremely fixed, non-flexible measurements like something tailored or a one-size only item.
