For gowns with a smaller circumference up to 125'' (318cm), a crinoline with a minimal amount of fullness is ideal. This type of crinoline usually has a non-stick layer under the tulle layer to prevent the tulle from scratching. Some crinolines have another non-stick layer on top of the tulle to prevent the tulle from snagging on the gown.
Medium fullness crinolines suit gowns with a hem circumference of 128'' to 157'' (325cm to 398.8cm). This type of crinoline is great for gowns which taper out from the waist to the hem without expanding at the hip line.
Full or Super full crinolines suit a hem circumference of 160'' to 188''(406.4cm to 477.5cm). This type of crinoline is great for gowns with embroidered designs which need to be accentuated or have layers of fabric such as tulle or a mixture of tulle and satin.
For gowns that are very full with circumferences up to 220'' (558.8cm), a mega full crinoline is more appropriate. This type of crinoline is great to achieve the ''Gone with the Wind'' look for ball or Elizabethan style gowns.
Never choose a crinoline that is fuller than your gown especially if you have not allowed any extra length in the skirt to accommodate a fuller crinoline. Also an over full skirt may take away the dramatic effect you wished to achieve. If, however, your gown is made of very heavy material and would squash a crinoline for the hem circumference it may pay to try a fuller crinoline to get the desired effect.
Hoops are another option which you may consider and are ideal for ball or very full gowns especially those with layers of tulle under the top skirt. They do have some disadvantages as they can alter the effect to the gown, especially if the hoops are not covered with tulle or thicker
fabric as they may show through the gown. They also have a tendency to swing when walking.
Which ever crinoline you choose however, it is best to choose one which you like, is appropriate for the style of gown you have chosen and also highlights the best features of your gown.
