Sizing is a big part of a shopper’s buying journey and therefore pricing is not something to consider lightly. But, did you know pricing correctly can impact your development costs?

Need help determining what sizes to offer for your items? Here are our thoughts!


Here are your sizing options:

  • Alpha sizing (XS, S, M, L, XL, etc)
  • Numeric sizing (0, 2, 4, 6, 8, 10, 12 etc)
  • One Size Fits All
  • Made-up Sizing (non-standard sizing)

One size fits all is probably only relevant if you are selling capes or accessories, so let’s strike that (although one-size is a great way to make production easier!).

Nineteenth Amendment does not allow brands to offer because it is another hurdle for the customer, so that leaves us with two options: Alpha and Numeric sizing.

  • PROS Alpha sizing (XS, S, M, L, XL, etc): Less size options means less cost spent on grading and making product.
  • PROS Numeric (0, 2,4,6,8,10,12 etc) : May offer better fit depending on your product.

If you are just getting started and want to reduce costs, we suggest Alpha sizing.

BUT WAIT – there’s more. There is also ‘plus size’ sizing. In the USA over 67% of women are a size 14 or larger so you are missing out on a lot of shoppers if you don’t offer plus sizes, but again – this all depends on your customer and product. Plus size products involve more fabric and different construction so they can be more costly to do product development for. Currently Nineteenth Amendment doesn’t offer plus size options since most designers aren’t trained in plus-size construction, but we’re working on it!


Menswear has different standards. For example, male shoppers are accustom to shopping for pants by waist size. For menswear sizing you have two options:

  • Alpha sizing (XS, S, M, L, XL, XXL …)
  • Numeric sizing (Waist sizes and neck sizes – often for button ups, suits, pants etc.)

For menswear generally, we suggest using Alpha sizing when possible. Once products are sized using numeric waist sizes (and length if you offer it), expectations of fit tend to increase.

But why don’t you let designers offer custom, made-to-order pieces?

Great question! We have  two great responses to that question.

  1. Custom sizing isn’t really scalable/cost efficient for the brands we work with.
  2. Custom/made-to-order sizing exponentially increases expectations of garments fitting perfectly, and – if you are a woman – you know fit is probably 80% psychological and only 20% a result of actual measurements. Perception of fit can change based on the type of fabric, the day, and even how happy you are. That’s a huge gamble to take if you are a brand! So unless you are making gowns (and offering alterations) at a high price point, stay away from custom (please!!!).
