Write a size guide for a WooCommerce apparel product line

Write the size guide for a WooCommerce apparel product line:

PRODUCT LINE: [Solstice high-waist leggings], sizes [XS-XXL]
FIT NOTE: [compression fit designed to be snug, not relaxed, brand runs about half a
size smaller than most mainstream activewear]
MEASUREMENTS AVAILABLE: [waist and hip measurements in inches for each size, taken
from the garment itself, not body measurements, currently missing from the product
page]
RETURN DATA: [size-related returns currently concentrated at the M/L boundary,
suggesting shoppers between those sizes are guessing wrong]

Write the size guide with:

1. A measurement table using actual body measurement ranges for waist and hip per size,
   not just relabeling S/M/L, since a shopper comparing their own tape-measure numbers
   to a table is far less likely to guess wrong than one comparing a T-shirt size from
   a different brand to this brand's label.
2. A clear statement of the fit itself (compression, snug by design) stated as a
   feature, not an apology, since burying "this runs small" as a disclaimer reads as
   defensive, while stating "designed for a snug, supportive compression fit, size up
   if you prefer more room" reads as a deliberate design choice.
3. Explicit sizing-between-sizes guidance at the exact boundary where returns are
   concentrated (M/L): a one-line rule like "if your waist measurement falls between
   the M and L range, size up for all-day wear or size down for a firmer compression
   feel," since generic "if between sizes, size up" advice doesn't account for the fact
   that compression wear is one of the few categories where some shoppers deliberately
   want the snugger of two sizes.
4. A short note recommending customers measure themselves rather than rely on their
   usual size in other brands, since activewear sizing varies more between brands than
   almost any other apparel category and "I usually wear a medium" is the single most
   common wrong assumption behind a return.

Replace the bracketed sizes, measurements, and return data with your own line's actual
numbers.
